Esports (also known as electronic sports, e-sports, or eSports) is a form of sport competition using video games. Esports often takes the form of organized, multiplayer video game competitions, particularly between professional players, individually or as teams. Although organized competitions have long been a part of video game culture, these were largely between amateurs until the late 2000s, when participation by professional gamers and spectatorship in these events through live streaming saw a large surge in popularity. By the 2010s, esports was a significant factor in the video game industry, with many game developers actively designing and providing funding for tournaments and other events.
The most common video game genres associated with esports are multiplayer online battle arena (MOBA), first-person shooter (FPS), fighting, card games, battle royales, and real-time strategy (RTS). Popular esport franchises include League of Legends, Dota, Counter-Strike, Overwatch, Super Smash Bros., and StarCraft, among many others. Tournaments such as the League of Legends World Championship, Dota 2's International, the fighting game-specific Evolution Championship Series (EVO) and Intel Extreme Masters are among the most popular in esports. Many other competitions use a series of league play with sponsored teams, such as the Overwatch League. Although the legitimacy of esports as a true sporting competition remains in question, they have been featured alongside traditional sports in some multinational events in Asia, with the International Olympic Committee also having discussed their inclusion into future Olympic events.
By the late 2010s, it was estimated that the total audience of esports would grow to 454 million viewers, with revenue increasing to over US$1 billion. The increasing availability of online streaming media platforms, particularly YouTube and Twitch, have become central to the growth and promotion of esports competitions. Despite viewership being approximately 85% male and 15% female, with a majority of viewers between the ages of 18 and 34, female gamers have also played professionally. The popularity and recognition of esports first took place in Asia, specifically in China and South Korea, with the latter having licensed professional players since 2000. Despite its large video game industry, esports in Japan is relatively underdeveloped, with this being largely attributed to its broad anti-gambling laws which prohibit paid professional gaming tournaments. Outside of Asia, esports are also popular in Europe and the Americas, with both regional and international events taking place in those regions.
Early history (1972–1989)
The earliest known video game competition took place on 19 October 1972 at Stanford University for the game Spacewar. Stanford students were invited to an "Intergalactic spacewar olympics" whose grand prize was a year's subscription for Rolling Stone, with Bruce Baumgart winning the five-man-free-for-all tournament and Tovar and Robert E. Maas winning the team competition.
The Golden age of arcade video games was heralded by Taito's Space Invaders in 1978, which popularized the use of a persistent high score for all players. Several video games in the next several years followed suit, adding other means of tracking high scores such with high score tables that included the players' initials in games like Asteroids in 1979. High score-chasing became a popular activity and a means of competition. The Space Invaders Championship held by Atari in 1980 was the earliest large scale video game competition, attracting more than 10,000 participants across the United States, establishing competitive gaming as a mainstream hobby. Walter Day owner of an arcade in Iowa, had taken it upon himself to travel across the United States to record the high scores on various games in 1980, and on his return, founded Twin Galaxies, a high score record-keeping organization. The organization went on to help promote video games and publicize its records through publications such as the Guinness Book of World Records, and in 1983 it created the U.S. National Video Game Team. The team was involved in competitions, such as running the Video Game Masters Tournament for Guinness World Records and sponsoring the North American Video Game Challenge tournament. A multicity tour in 1983, the "Electronic Circus", was used to feature these players in live challenges before audiences, and draw more people to video games. These video game players and tournaments were featured in well-circulated newspapers and popular magazines including Life and Time and became minor celebrities at the time, such as Billy Mitchell. Besides establishing the competitive nature of games, these types of promotional events all formed the nature of the marketing and promotion that formed the basis of modern esports.
Televised esports events aired during this period included the American show Starcade which ran from 1982–1984 airing a total of 133 episodes, on which contestants would attempt to beat each other's high scores on an arcade game. A video game tournament was included as part of TV show That's Incredible!, and tournaments were also featured as part of the plot of various films, including 1982's Tron. In the UK, the BBC game show First Class included competitive video game rounds featuring the contemporary arcade games, such as Hyper Sports, 720° and Paperboy.
The 1988 game Netrek was an Internet game for up to 16 players, written almost entirely in cross-platform open source software. Netrek was the third Internet game, the first Internet game to use metaservers to locate open game servers, and the first to have persistent user information. In 1993 it was credited by Wired Magazine as "the first online sports game".
Growth and online video games (1990–1999)
The fighting game Street Fighter II (1991) popularized the concept of direct, tournament-level competition between two players. Previously, video games most often relied on high scores to determine the best player, but this changed with Street Fighter II, where players would instead challenge each other directly, "face-to-face," to determine the best player, paving the way for the competitive multiplayer and deathmatch modes found in modern action games. The popularity of fighting games such as Street Fighter and Marvel vs. Capcom in the 1990s led to the foundation of the international Evolution Championship Series (EVO) esports tournament in 1996.
Large esports tournaments in the 1990s include the 1990 Nintendo World Championships, which toured across the United States, and held its finals at Universal Studios Hollywood in California. Nintendo held a 2nd World Championships in 1994 for the Super Nintendo Entertainment System called the Nintendo PowerFest '94. There were 132 finalists that played in the finals in San Diego, California. Mike Iarossi took home 1st prize. Blockbuster Video also ran their own World Game Championships in the early 1990s, co-hosted by GamePro magazine. Citizens from the United States, Canada, the United Kingdom, Australia, and Chile were eligible to compete. Games from the 1994 championships included NBA Jam and Virtua Racing.
Television shows featuring esports during this period included the British shows GamesMaster and Bad Influence! the Australian game show A*mazing, where in one round contestants competed in a video game face off, and the Canadian game show Video & Arcade Top 10.
In the 1990s, many games benefited from increasing internet connectivity, especially PC games. Tournaments established in the late 1990s include the Cyberathlete Professional League (CPL), QuakeCon, and the Professional Gamers League. PC games played at the CPL included the Counter-Strike series, Quake series, StarCraft, and Warcraft.
Global tournaments (2000–present)
The growth of esports in South Korea is thought to have been influenced by the mass building of broadband Internet networks following the 1997 Asian financial crisis. It is also thought that the high unemployment rate at the time caused many people to look for things to do while out of work. Instrumental to this growth of esports in South Korea was the prevalence of the Komany-style internet café/LAN gaming center, known as a PC bang. The Korean e-Sports Association, an arm of the Ministry of Culture, Sports and Tourism, was founded in 2000 to promote and regulate esports in the country.
"Evo Moment 37", also known as the "Daigo Parry", refers to a portion of a Street Fighter III: 3rd Strike semi-final match held at Evolution Championship Series 2004 (Evo 2004) between Daigo Umehara and Justin Wong. During this match, Umehara made an unexpected comeback by parrying 15 consecutive hits of Wong's "Super Art" move while having only one pixel of vitality. Umehara subsequently won the match. "Evo Moment #37" is frequently described as the most iconic and memorable moment in the history of competitive video gaming. Being at one point the most-watched competitive gaming moment of all time, it has been compared to sports moments such as Babe Ruth's called shot and the Miracle on Ice.
In April 2006 the G7 teams federation were formed by seven prominent Counter-Strike teams. The goal of the organization was to increase stability in the esports world, particularly in standardizing player transfers and working with leagues and organizations. The founding members were 4Kings, Fnatic, Made in Brazil, Mousesports, NiP, SK-Gaming, Team 3D. The organization only lasted until 2009 before dissolving.
The 2000s was a popular time for televised esports. Television coverage was best established in South Korea, with StarCraft and Warcraft III competitions regularly televised by dedicated 24-hour cable TV game channels Ongamenet and MBCGame. Elsewhere, esports television coverage was sporadic. The German GIGA Television covered esports until its shutdown in 2009. The United Kingdom satellite television channel XLEAGUE.TV broadcast esports competitions from 2007 to 2009. The online esports only channel ESL TV briefly attempted a paid television model renamed GIGA II from June 2006 to autumn 2007. The French channel Game One broadcast esports matches in a show called Arena Online for the Xfire Trophy. The United States channel ESPN hosted Madden NFL competitions in a show called Madden Nation from 2005 to 2008. DirecTV broadcast the Championship Gaming Series tournament for two seasons in 2007 and 2008. CBS aired prerecorded footage of the 2007 World Series of Video Games tournament that was held in Louisville, Kentucky. The G4 television channel originally covered video games exclusively, but broadened its scope to cover technology and men's lifestyle, though has now shutdown.
During the 2010s, esports grew tremendously, incurring a large increase in both viewership and prize money. Although large tournaments were founded before the 21st century, the number and scope of tournaments has increased significantly, going from about 10 tournaments in 2000 to about 260 in 2010. Many successful tournaments were founded during this period, including the World Cyber Games, the Intel Extreme Masters, and Major League Gaming. The proliferation of tournaments included experimentation with competitions outside traditional esports genres. For example, the September 2006 FUN Technologies Worldwide Webgames Championship featured 71 contestants competing in casual games for a $1 million grand prize.
The popularity and emergence of online streaming services have helped the growth of esports in this period, and are the most common method of watching tournaments. Twitch, an online streaming platform launched in 2011, routinely streams popular esports competitions. In 2013, viewers of the platform watched 12 billion minutes of video on the service, with the two most popular Twitch broadcasters being League of Legends and Dota 2. During one day of The International, Twitch recorded 4.5 million unique views, with each viewer watching for an average of two hours.
The modern esports boom has also seen a rise in video games companies embracing the esports potential of their products. After many years of ignoring and at times suppressing the esports scene, Nintendo hosted Wii Games Summer 2010. Spanning over a month, the tournament had over 400,000 participants, making it the largest and most expansive tournament in the company's history. In 2014 Nintendo hosted an invitational Super Smash Bros. for Wii U competitive tournament at the 2014 Electronic Entertainment Expo (E3) press conference that was streamed online on Twitch. Halo developers 343 Industries announced in 2014 plans to revive Halo as an esport with the creation of the Halo Championship Series and a prize pool of US$50,000. Both Blizzard Entertainment and Riot Games have their own collegiate outreach programs with their North American Collegiate Championship. Since 2013 universities and colleges in the United States such as Robert Morris University Illinois and the University of Pikeville have recognized esports players as varsity level athletes and offer athletic scholarships. In 2017, Tespa, Blizzard Entertainment's collegiate esports division, unveiled its new initiative to provide scholarships and prizes for collegiate esports clubs competing in its tournaments worth US$1 million. Colleges have begun granting scholarships to students who qualify to play esports professionally for the school. Colleges such as Columbia College, Robert Morris University, and Indiana Institute of Technology have taken part in this. In 2018, Harrisburg University of Science and Technology began a tuition scholarship program for esports players.
Physical viewership of esports competitions and the scope of events have increased in tandem with the growth of online viewership. In 2013, the Season 3 League of Legends World Championship was held in a sold-out Staples Center. The 2014 League of Legends World Championship in Seoul, South Korea, had over 40,000 fans in attendance and featured the band Imagine Dragons, and opening and closing ceremonies in addition to the competition.
Classification as a sport
Labeling video games as sports is a controversial point of debate. While some point to the growth in popularity of esports as justification for designating some games as sports, others contend that video games will never reach the status of "true sports". However popularity is not the only reason identified: some have argued that "careful planning, precise timing, and skillful execution" ought to be what classifies an activity as sport, and that physical exertion and outdoor playing areas are not required by all traditional or non-traditional "sports". In a 2014 technology conference, when asked about the recent buyout of popular game streaming service Twitch, ESPN president John Skipper described esports as "not a sport – [they're] a competition." In 2013 on an episode of Real Sports with Bryant Gumbel the panelist openly laughed at the topic. In addition, many in the fighting games community maintain a distinction between their competitive gaming competitions and the more commercially connected esports competitions of other genres. Video games are sometimes classified as a mind sport. In the 2015 World Championship hosted by the International Esports Federation, an esports panel was hosted with guests from international sports society to discuss the future recognition of esports as a recognized, legitimate sporting activity worldwide.
China was one of the first countries to recognize esport as a real sport in 2003, despite concerns at the time that video games were addicting. Through this, the government encouraged esport, stating that by participating in esports, players were also "training the body for China". Further, by early 2019, China recognized esports players as an official profession within the Ministry of Human Resources and Social Security's Occupation Skill Testing Authority recommendations, as well as professional gaming operators, those that distribute and manage esports games. By July 2019, more than 100,000 people had registered themselves as professional gamers under this, with the Ministry stating that they anticipate over 2 million such people in this profession in five years. In August 2020, Beijing announced it would convert Shougang Park, an old steel production zone, into an e-sports park.
In 2016, the French government started working on a project to regulate and recognize esports. The Games and Amusements Board of the Philippines started issuing athletic license to Filipino esports players who are vouched by a professional esports team in July 2017.
To help promote esports as a legitimate sport, several esports events have been run alongside more traditional international sports competitions. The 2007 Asian Indoor Games was the first notable multi-sport competition including esports as an official medal-winning event alongside other traditional sports, and the later editions of the Asian Indoor Games and its successor the Asian Indoor and Martial Arts Games have always included esports as an official medal event or an exhibition event up to now. Moreover, the Asian Games, which is the Asian top-level multi-sport competition, will also include esports as a medal event at the 2022 edition; esports around games such as Hearthstone, Starcraft II, and League of Legends were presented as an exhibition event at the 2018 Asian Games as a lead-in to the 2022 games. The 2019 Southeast Asian Games included six medal events for esports.
Olympic Games recognition
The Olympic Games are also seen as a potential method to legitimize esports. A summit held by the International Olympic Committee (IOC) in October 2017 acknowledged the growing popularity of esports, concluding that "Competitive 'esports' could be considered as a sporting activity, and the players involved prepare and train with an intensity which may be comparable to athletes in traditional sports" but would require any games used for the Olympics fitting "with the rules and regulations of the Olympic movement". Another article by Andy Stout suggests that 106 million people viewed the 2017 Worlds Esports competition. These are the kind of figures that are making people around the world as well as broadcasters sit up in their seats and take notice. The sporting world is changing! Esports is becoming so large that even the International Olympic committee (IOC) is beginning to host events. Two difficulties remain for presenting esports as an Olympic event according to IOC President Thomas Bach: that they would need to restrict those that present violent gameplay, and that there is currently a lack of a global sanctioning body for esports to coordinate further. On the issue of violence, while Bach acknowledged that many Olympic sports bore out from actual violent combat, "sport is the civilized expression about this. If you have egames where it’s about killing somebody, this cannot be brought into line with our Olympic values." Due to that, it was suggested that the IOC would approve more of esports centered around games that simulate real sports, such as the NBA 2K or FIFA series.
The issues around esports have not prevented the IOC from exploring what possibilities there are for incorporation into future Olympics. During July 2018, the IOC and the Global Association of International Sports Federations (GAISF) held a symposium and inviting major figures in esports, including Epic Games' Mark Rein, Blizzard Entertainment's Mike Morhaime, and esports players Dario "TLO" Wünsch, Jacob "Jake" Lyon, and Se-yeon "Geguri" Kim, for these organizations "to gain a deeper understanding of esports, their impact and likely future development, so that [they] can jointly consider the ways in which [they] may collaborate to the mutual benefit of all of sport in the years ahead". The IOC has tested the potential for esports through exhibition games. With support of the IOC, Intel sponsored exhibition esport events for StarCraft II and Steep prior to the 2018 Winter Olympics in Pyeongchang, and five South Korean esport players were part of the Olympic Torch relay. A similar exhibition showcase, the eGames, was held alongside the 2016 Summer Olympics in Rio de Janeiro, though this was not supported by the IOC.
Leaders in Japan are becoming involved to help bring esports to the 2020 Summer Olympics and beyond, given the country's reputation as a major video game industry center. Esports in Japan had not flourished due to the country's anti-gambling laws that also prevent paid professional gaming tournaments, but there were efforts starting in late 2017 to eliminate this issue. At the suggestion of the Tokyo Olympic Games Committee for the 2020 Summer Olympics, four esports organizations have worked with Japan's leading consumer organization to exempt esports tournaments from gambling law restrictions. Takeo Kawamura, a member of the Japanese House of Representatives and of the ruling Liberal Democratic Party, led a collation of ruling and opposing politicians to support esports, called the Japan esports Union, or JeSU; Kawamura said that they would be willing to pass laws to further exempt esports as needed so that esports athletes can make a living playing these sports. So far, this has resulted in the ability of esports players to obtain exemption licenses to allow them to play, a similar mechanism needed for professional athletes in other sports in Japan to play professionally. The first such licenses were given out in mid-July 2018, via a tournament held by several video game publishers to award prizes to many players but with JeSU offered these exemption licenses to the top dozen or so players that emerge, allowing them to compete in further esports events. The Tokyo Olympic Committee has also planned to arrange a number of esports events to lead up into the 2020 games.
The organization committee for the 2024 Summer Olympics in Paris were in discussions with the IOC and the various professional esport organizations to consider esports for the event, citing the need to include these elements to keep the Olympics relevant to younger generations. Ultimately, the organization committee determined esports were premature to bring to the 2024 Games as medal events, but have not ruled out other activities related to esports during the Games.
During the Eighth Olympic Summit in December 2019, the IOC reiterated that it would only consider sports-simulating games for any official Olympic event, but it would look at two paths for such games in the future: those that promoted good physical and mental health lifestyles, and virtual reality and augmented reality games that included physical activity.
A number of games are popular among professional competitors. The tournaments which emerged in the mid-1990s coincided with the popularity of fighting games and first-person shooters, genres which still maintain a devoted fan base. In the 2000s, real-time strategy games became overwhelmingly popular in South Korean internet cafés, with crucial influence on the development of esports worldwide. Competitions exist for many titles and genres, though the most popular games as of the late 2010s are Counter-Strike: Global Offensive, Call of Duty, League of Legends, Dota 2, Smite, Rocket League, Heroes of the Storm, Hearthstone, Super Smash Bros. Melee, StarCraft II and Overwatch. Hearthstone has also popularized the digital collectible card game (DCCG) genre since its release in 2014.
Video game design
While it is common for video games to be designed with the experience of the player in game being the only priority, many successful esports games have been designed to be played professionally from the beginning. Developers may decide to add dedicated esports features, or even make design compromises to support high level competition. Games such as StarCraft II, League of Legends, and Dota 2 have all been designed, at least in part, to support professional competition.
In addition to allowing players to participate in a given game, many game developers have added dedicated observing features for the benefit of spectators. This can range from simply allowing players to watch the game unfold from the competing player's point of view, to a highly modified interface that gives spectators access to information even the players may not have. The state of the game viewed through this mode may tend to be delayed by a certain amount of time in order to prevent either teams in a game from gaining a competitive advantage. Games with these features include Counter-Strike: Global Offensive, Call of Duty, StarCraft II, Dota 2, and Counter-Strike. League of Legends includes spectator features, which are restricted to custom game modes.
A very common method for connection is the Internet. Game servers are often separated by region, but high quality connections allow players to set up real-time connections across the world. Downsides to online connections include increased difficulty detecting cheating compared to physical events, and greater network latency, which can negatively impact players' performance, especially at high levels of competition. Many competitions take place online, especially for smaller tournaments and exhibition games.
Since the 1990s, professional teams or organized clans have set up matches via Internet Relay Chat networks such as QuakeNet. As esports have developed, it has also become common for players to use automated matchmaking clients built into the games themselves. This was popularized by the 1996 release of Blizzard's Battle.net, which has been integrated into both the Warcraft and StarCraft series. Automated matchmaking has become commonplace in console gaming as well, with services such as Xbox Live and the PlayStation Network. After competitors have contacted each other, the game is often managed by a game server, either remotely to each of the competitors, or running on one of the competitor's machines.
Local area network
Additionally, competitions are also often conducted over a local area network or LAN. The smaller network usually has very little lag and higher quality. Because competitors must be physically present, LANs help ensure fair play by allowing direct scrutiny of competitors. This helps prevent many forms of cheating, such as unauthorized hardware or software modding. The physical presence of competitors helps create a more social atmosphere at LAN events. Many gamers organize LAN parties or visit Internet cafés, and most major tournaments are conducted over LANs.
Individual games have taken various approaches to LAN support. In contrast to the original StarCraft, StarCraft II was released without support for LAN play, drawing some strongly negative reactions from players. League of Legends was originally released for online play only, but announced in October 2012 that a LAN client was in the works for use in major tournaments. In September 2013, Valve added general support for LAN play to Dota 2 in a patch for the game.
Players and teams
Professional gamers, or "pro gamers", are often associated with gaming teams and/or broader gaming associations. Teams like FaZe Clan, 100 Thieves, Evil Geniuses, Team SoloMid, Cloud9, Fnatic, Mineski, Counter Logic Gaming, T1, G2 Esports, Team Envy, and Natus Vincere consist of several professionals. These teams often cover multiple esports games within tournaments and leagues, with various team makeups for each game. They may also represent single players for one-on-one esports games like fighting games within Evolution Championship Series, or Hearthstone tournaments. In addition to prize money from tournament wins, players in these teams and associations may also be paid a separate team salary. Team sponsorship may cover tournament travel expenses or gaming hardware. Prominent esports sponsors include companies such as Logitech and Razer. Teams feature these sponsors on their website, team jerseys and on their social media, in 2016 the biggest teams have social media followings of over a million. Associations include the Korean e-Sports Association (KeSPA), the International e-Sports Federation (IeSF), the British esports Association, and the World esports Association (WESA).
Some traditional sporting athletes have invested in esports, such as Rick Fox's ownership of Echo Fox, Jeremy Lin's ownership of Team VGJ, Shaquille O'Neal's investment in NRG Esports. Some association football teams, such as FC Schalke 04 in Germany, Paris Saint-Germain esports in France; Besiktas JK, Fenerbahce S.K., and Galatasaray in Turkey; Panathinaikos F.C. in Greece either sponsor or have complete ownership in esports teams.
The training that the players must undergo to prepare for tournaments is different but still takes a tremendous amount of time. Athletes from traditional sports' training is almost entirely based on honing their physical prowess in performing that sport, such as muscle memory, exercising, and dieting. Esports athletes' training is much more based on training the mind, such as studying strategies and new updates for the game. Team Liquid, a professional League of Legends team, practice for a minimum of 50 hours per week and most play the game far more. This training schedule for players has resulted in many of them retiring an early age. Few careers burn as intensely—and as briefly—as that of an esports professional. Players are generally in competition by their mid- to late-teens, with most retiring by their late-20s.
Leagues and tournaments
Promotion and relegation leagues
In most team-based esports, organized play is centered around the use of promotion and relegation to move sponsored teams between leagues within the competition's organization based on how the team fared in matches; this follows patterns of professional sports in European and Asian countries. Teams will play a number of games across a season as to vie for top positioning in the league by the end of that season. Those that do well, in addition to prize money, may be promoted into a higher-level league, while those that fare poorly can be regulated downward. For example, until 2018 Riot Games runs several League of Legends series, with the League of Legends Championship Series being the top-tier series. Teams that did not do well were relegated to the League of Legends Challenger Series, replaced by the better performing teams from that series. This format was discontinued when Riot opted to use the franchise format in mid-2018.
With rising interest in viewership of esports, some companies sought to create leagues that followed the franchise approach used in North American professional sports, in which all teams, backed by a major financial sponsor to support the franchise, participate in a regular season of matches to vie for top standing as to participate in the post-season games. This approach is more attractive for larger investors, who would be more willing to back a team that remains playing in the esport's premiere league and not threatened to be relegated to a lower standing. Though the details vary from league to league, these leagues generally require all signed player to have a minimum salary with appropriate benefits, and may share in the team's winnings. While there is no team promotion or relegation, players can be signed onto contracts, traded among teams, or let go as free agents, and new players may be pulled from the esports' equivalent minor league.
The first such league to be formed was the Overwatch League, established by Blizzard Entertainment in 2016 based on its Overwatch game. Initially launched in 2018 with 12 teams, the league expanded to twenty teams in 2019. Though the first two seasons were played at Blizzard Arena in Los Angeles, the Overwatch League's third season in 2020 will implement the typical home/away game format at esports arenas in the teams' various home cities or regions.
Take-Two Interactive partnered with the National Basketball Association (NBA) to create the NBA 2K League, using the NBA 2K game series. It is the first esports league to be operated by a professional sports league, and the NBA sought to have a League team partially sponsored by each of the 30 professional NBA teams. Its inaugural season is set to start May 2018 with 17 teams. Similarly, EA Sports and Major League Soccer (MLS) established the eMLS in 2018, a league using EA's FIFA series.
Cloud9 and Dignitas, among others, have started development of a franchise-based Counter-Strike: Global Offensive league, Flashpoint, in February 2020. This will be the first such esports league to be owned by the teams rather than any single organization.
Esports are also frequently played in tournaments, where potential players and teams vie to be placed through qualification matches before entering the tournament. From there, the tournament formats can vary from single or double elimination, sometimes hybridized with group stage. Esports tournaments are almost always physical events in which occur in front of a live audience, with referees or officials to monitor for cheating. The tournament may be part of a larger gathering, such as Dreamhack, or the competition may be the entirety of the event, like the World Cyber Games or the Fortnite World Cup. Esport competitions have also become a popular feature at gaming and multi-genre conventions.
Although competitions involving video games have long existed, esports underwent a significant transition in the late 1990s. Beginning with the Cyberathlete Professional League in 1997, tournaments became much larger, and corporate sponsorship became more common. Increasing viewership both in person and online brought esports to a wider audience. Major tournaments include the World Cyber Games, the North American Major League Gaming league, the France-based Electronic Sports World Cup, and the World e-Sports Games held in Hangzhou, China.
The average compensation for professional esports players does not compare to those of the top classical sports organizations in the world. According to Julian Krinsky Camps & Programs website, the top Esports player in the world earned around $2.5 million in 2017. The highest overall salary by any esports professional at the time was around $3.6 million. While prizes for esports competitions can be very large, the limited number of competitions and large number of competitors ultimately lowers the amount of money one can make in the industry. In the United States, Esports competitions have prizes that can reach $200,000 for a single victory. Dota 2 International hosted a competition where the grand-prize winning team walked home with almost $10.9 million.
For well established games, total prize money can amount to millions of U.S. dollars a year. As of 10 September 2016, Dota 2 has awarded approximately US$86 million in prize money within 632 registered tournaments, with 23 players winning over $1 million. League of Legends awarded approximately $30 million within 1749 registered tournaments, but in addition to the prize money, Riot Games provides salaries for players within their League of Legends Championship Series. Nonetheless, there has been criticism to how these salaries are distributed, since most players earn a fairly low wage but a few top players have a significantly higher salary, skewing the average earning per player. In August 2018, The International 2018, Valve's annual premier Dota 2 tournament, was held and broke the record for holding the largest prize pool to date for any esports tournament, amounting to over US$25 million.
Often, game developers provide prize money for tournament competition directly, but sponsorship may also come from third parties, typically companies selling computer hardware, energy drinks, or computer software. Generally, hosting a large esports event is not profitable as a stand-alone venture. For example, Riot has stated that their headline League of Legends Championship Series is "a significant investment that we're not making money from".
There is considerable variation and negotiation over the relationship between video game developers and tournament organizers and broadcasters. While the original StarCraft events emerged in South Korea largely independently of Blizzard, the company decided to require organizers and broadcasters to authorize events featuring the sequel StarCraft II. In the short term, this led to a deadlock with the Korean e-Sports Association. An agreement was reached in 2012. Blizzard requires authorization for tournaments with more than US$10,000 in prizes. Riot Games offers in-game rewards to authorized tournaments.
Collegiate and school leagues
In addition to professional and amateur esports, esports have drawn attention of colleges and high schools since 2008.
Along with the bursting popularity of Esports over the last two decades came a demand for extended opportunities for Esport's athletes. Universities across the world (mostly China and America) began offering scholarship opportunities to incoming freshmen to join their collegiate Esports teams. According to Schaeperkoetter (2017) and others, the potential impact that an eSports program could have on a university, coupled with the growing interest that universities are showing in such a program, combine to make this line of research relevant in sport literature.
As of 2019, over 130 colleges has esports-based variety programs.
While game publishers or esport broadcasters typically act in oversight roles for specific esports, a number of esport governing bodies have been established to collectively represent esports on a national, regional or global basis. These governing bodies may have various levels of involvement with the esport, from being part of esports regulation to simply acting more as a trade group and public face for esports.
The International Esports Federation (IESF) was one of the first such bodies. Originally formed in 2008 to help promote esports in the southeast Asian region, it has grown to include 56 member countries from across the global. The IESF has managed annual Esport World Championships for teams from its member countries across multiple games.
The European Esports Federation was formed in April 2019 and includes UK, Belgium, Germany, Austria, Hungary, France, Russia, Slovenia, Serbia, Sweden, Turkey, and Ukraine. This body was designed more to be a managing partner for other esports, working to coordinate event structures and regulations across multiple esports.
Additionally, trade groups representing video games have also generally acted as governing bodies for esports. Notably, in November 2019, five major national trade organizations - the Entertainment Software Association in the United States, the Entertainment Software Association of Canada, The Association for UK Interactive Entertainment, Interactive Software Federation of Europe, and the Interactive Games and Entertainment Association of Australian and New Zealand - issued a joined statement for supporting the promotion and participation of esports to respect player safety and integrity, respect and diversity among players, and enriching game play.
Ethics and legal problems
Pro gamers are usually obligated to behave ethically, abiding by both the explicit rules set out by tournaments, associations, and teams, as well as following general expectations of good sportsmanship. For example, it is common practice and considered good etiquette to chat "gg" (for "good game") when defeated. Many games rely on the fact competitors have limited information about the game state. In a prominent example of good conduct, during a 2012 IEM StarCraft II game, the players Feast and DeMusliM both voluntarily offered information about their strategies to negate the influence of outside information inadvertently leaked to "Feast" during the game. Players in some leagues have been reprimanded for failure to comply with expectations of good behavior. In 2012 professional League of Legends player Christian "IWillDominate" Riviera was banned from competing for a period of one year following a history of verbal abuse. In 2013 StarCraft II progamer Greg "Idra" Fields was fired from Evil Geniuses for insulting his fans on the Team Liquid internet forums. League of Legends players Mithy and Nukeduck received similar penalties in 2014 after behaving in a "toxic" manner during matches.
Team Siren, an all-female League of Legends team, was formed in June 2013. The announcement of the team was met with controversy, being dismissed as a "gimmick" to attract the attention of men. The team disbanded within a month, due to the negative publicity of their promotional video, as well as the poor attitude of the team captain towards her teammates.
There have been serious violations of the rules. In 2010, eleven StarCraft: Brood War players were found guilty of fixing matches for profit, and were fined and banned from future competition. Team Curse and Team Dignitas were denied prize money for collusion during the 2012 MLG Summer Championship. In 2012, League of Legends team Azubu Frost was fined US$30,000 for cheating during a semifinal match of the world playoffs. Dota 2 player Aleksey "Solo" Berezin was suspended from a number of tournaments for intentionally throwing a game in order to collect $322 from online gambling. In 2014, four high-profile North American Counter-Strike players from iBuyPower, namely Sam "DaZeD" Marine, Braxton "swag" Pierce, Joshua "steel" Nissan and Keven "AZK" Lariviere were suspended from official tournaments after they had been found guilty of match-fixing. The four players had allegedly profited over US$10,000 through betting on their fixed matches. Gambling on esports using Counter-Strike: Global Offense "skins", worth an estimated US$2.3 billion in 2015, had come under criticism in June and July 2016 after several questionable legal and ethical aspects of the practice were discovered.
Reports of widespread use of performance-enhancing drugs (PEDs) in esports are not uncommon, with players discussing their own, their teammates' and their competitors' use and officials acknowledging the prevalence of the issue. Players often turn to stimulants such as Ritalin, Adderall and Vyvanse, drugs which can significantly boost concentration, improve reaction time and prevent fatigue. Selegiline, a drug used to treat Parkinson's disease, is reportedly popular because, like stimulants, it enhances mood and motivation. Conversely, drugs with calming effects are also sought after. Some players take propranolol, which blocks the effects of adrenaline, or Valium, which is prescribed to treat anxiety disorder, in order to remain calm under pressure. According to Bjoern Franzen, a former SK Gaming executive, it is second nature for some League of Legends players to take as many as three different drugs before competition. In July 2015 Kory "Semphis" Friesen, an ex-Cloud9 player, admitted that he and his teammates were all using Adderall during a match against Virtus.pro in the ESL One Katowice 2015 Counter-Strike: Global Offensive tournament, and went on to claim that "everyone" at ESEA League tournaments uses Adderall. in 2020 former Call of Duty champion Adam “KiLLa” Sloss told the Washington Post that one of the reasons he stopped competing in Esports was due to rampant drug use.
The unregulated use of such drugs poses severe risks to competitors' health, including addiction, overdose, serotonin syndrome and, in the case of stimulants, weight loss. Even over-the-counter energy drinks which are marketed specifically toward gamers have faced media and regulatory scrutiny due to deaths and hospitalizations. Accordingly, Adderall and other such stimulants are banned and their use penalized by many professional sporting bodies and leagues, including Major League Baseball and the National Football League. Although International e-Sports Federation (IeSF) is a signatory of the World Anti-Doping Agency, the governing body has not outlawed any PEDs in its sanctioned competitions. Action has been taken on the individual league level, however, as at least one major league, the Electronic Sports League, has made use of any drugs during matches punishable by expulsion from competition. Although not all players use drugs, it is common to see gamers use energy boosters or drinks. They commonly drink caffeinated drinks or use energy pills.
There has been some concern over the quality of life and potential mistreatment of players by organizations, especially in South Korea. Korean organizations have been accused of refusing to pay competitive salaries, leading to a slow exodus of Korean players to other markets. In an interview, League of Legends player Bae "Dade" Eo-jin said that "Korean players wake up at 1 pm and play until 5 am", and suggested that the 16-hour play schedule was a significant factor in causing burnout. Concerns over the mental health of players intensified in 2014 when League of Legends player Cheon "Promise" Min-Ki attempted suicide a week after admitting to match fixing.
To combat the negative environment, Korean League of Legends teams were given new rules for the upcoming 2015 season by Riot Games, including the adoption of minimum salaries for professional players, requiring contracts and allowing players to stream individually for additional player revenue.
Players must handle their own treatments and carry their own medical insurance, which is the opposite of the norm with professional sports teams. Since most esports play requires many actions per minute, some players may get repetitive strain injuries, causing hand or wrist pain.
League of Legends Championship Series and League of Legends Champions Korea offer guaranteed salaries for players. Despite this, online streaming is preferred by some players, as it is in some cases more profitable than competing with a team and streamers have the ability to determine their own schedule. The International tournament awards US$10 million to the winners, however teams that do not have the same amount of success often do not have financial stability and frequently break up after failing to win.
In 2015 it was estimated by SuperData Research that the global esports industry generated revenue of around US$748.8 million that year. Asia is the leading esports market with over $321 million in revenue, North America is around $224 million, and Europe has $172 million and the rest of the world for about $29 million. Global esports revenue is estimated to reach $1.9 billion by 2018.
The number of female viewers has been growing in esports, with an estimated 30% of esports viewers being female in 2013, an increase from 15% from the previous year. However, despite the increase in female viewers, there is not a growth of female players in high level competitive esports. The top female players that are involved in esports mainly get exposure in female-only tournaments, most notably Counter-Strike, Dead or Alive 4, and StarCraft II. All-female esports teams include Frag Dolls and PMS Clan.

Gambling and betting on esport matches have generally been illegal in major markets. The illegality of esport gambling has created a black market and virtual currency. And since it is not regulated, this may encourage match-fixing by players themselves, and lead to issues with underage gambling due to the draw of video games. A bright example can be represented by skin gambling, where virtual items earned in games are used as a currency, and it let users bet on the outcome of matches.
Esports gambling in the United States has been illegal under the federal Professional and Amateur Sports Protection Act of 1992 (PASPA) until May 2018. The Act prevented all but five states from allowing gambling on sporting events. However, regulation of esports betting still depended on state law. Some betting houses in Nevada, where sports betting has been already exempted under PASPA, classify esports as non-competitive "other events" similar to the selection of the Heisman Trophy winner or NFL Draft which are considered as legal. Other companies established in the United States allow betting on esports to international users but are restricted to Americans. Nevada legalized esports gambling in June 2017, classifying esports alongside with competitive sports and dog racing.
With the Supreme Court of the United States's ruling in Murphy v. National Collegiate Athletic Association in May 2018, PASPA was recognized as unconstitutional, as the Court claimed that the federal government cannot limit states from regulating sports betting. This created the potential for legalized esports-based betting in the United States. However, New Jersey, the state at the center of the Supreme Court case, passed its bill to legalize sports gambling but restricted gambling on esports to only international competitions where most players are over 18 years of age. Without PASPA, interstate gambling on esports would be still be limited by the Federal Wire Act, preventing users from betting on national esports events outside of the state.
In 2019, the countries where esports gambling is legal include the UK, New Zealand, Australia, China, Spain, Canada, South Korea, and Japan, and many of them are the international hosts for gaming tournaments. Also by the end of 2019, the state of New Jersey approved esports betting, just in time for the finals of the LoL Worlds Cup 2019 final match, which had over 4.000.000 spectators.
The incentives of the industry
Just as it happens with traditional sports, bookmarkers and gambling companies do their best to attract as many gamblers as possible. Yet, one of the biggest issues with the esports gambling industry has been its target audience. Thus, as an important part of the esports audience is underage most governments have been a bit skeptical regarding this market's moral view. Nevertheless, a huge synergy has been shown between the esports and gambling industries as online betting houses have been able to aim to younger audiences and experiment with new forms of gambling adapted to each game title and/or tournament. Furthermore, these industries have got so close that there are even betting houses sponsoring professional esports teams, as happened with the contract between Betway and PSG.LGD team (Dota 2) in August 2019.
Types of esports Gambling
As far as esports gambling goes, most of the bets move within the same nature as they do with traditional sports. Therefore, most gambling sites offering the booker service allow users to bet based on the outcome of tournaments, matches or special esports titles. On the other hand, due to the nature of esports, there are plenty of innovative ways to bet, which are based on in-game milestones. For example, League of Legend bettors may place their money on which team/champion will take the "First Blood". On the other hand, First-person shooters like Counter-Strike: Global Offensive is also open to "First Map" bets. Besides, some bookers allow "odds & even" bets which allow players to take chances on whether the final count of a game, mostly in kills, will be an odd or even number. Furthermore, there are different types of betting in esports based on the means of the bet. While an important part of this market is guided by bookers, some games allow bets in their in-game currency. On the other hand, players may stablish to do in-game or offline transactions to cover personal bets on the matches they participate in.
Data analytics and machine learning
With the growing popularity of machine learning in data analytics, esports has been the focus of several software programs that analyze the plethora of game data available. Based on the huge number of matches played on a daily basis globally (League of Legends alone had a reported 100 million active monthly players worldwide in 2016 and an average of 27 million League of Legends games played per day reported in 2014), these games can be used for applying big-data machine learning platforms. Several games make their data publicly available, so websites aggregate the data into easy-to-visualize graphs and statistics. In addition, several programs use machine learning tools to predict the win probability of a match based on various factors, such as team composition. In 2018, the DotA team Team Liquid partnered with a software company to allow players and coaches to predict the team's success rate in each match and provide advice on what needs to be changed to improve performance.
As more esport competitions and leagues are run entirely or in portion by the video game publisher or developer for the game, the ongoing viability of that game's esport activities is tied to that company. In December 2018, Blizzard announced that it was reducing resources spent on the development of Heroes of the Storm and canceling its plans for tournaments in 2019. This caused several professional Heroes players and coaches recognizing their career was no longer viable, and expressed outrage and disappointment at Blizzard's decision.
The main medium for esports coverage is the Internet. In the mid-2010s, mainstream sports and news reporting websites, such as ESPN, Yahoo!, Sport1, Kicker, and Aftonbladet started dedicated esports coverage. esports tournaments commonly use commentators or casters to provide live commentary of games in progress, similar to a traditional sports commentator. For popular casters, providing commentary for esports can be a full-time position by itself. Prominent casters for StarCraft II include Dan "Artosis" Stemkoski and Nick "Tasteless" Plott.
In 2018, the Associated Press' AP Stylebook officially began spelling the word as "esports", dropping support for both the capital "S" and the dash between "e" and "sports" styles, similar to how "e-mail" transformed with common usage to "email". Richard Tyler Blevins, better known as "Ninja", became the first professional gamer to appear in a cover story for a major sports magazine when he appeared in the September 2018 issue of ESPN The Magazine.
Internet live streaming
Many esports events are streamed online to viewers over the internet. With the shutdown of the Own3d streaming service in 2013, Twitch is by far the most popular streaming service for esports, competing against other providers such as Hitbox.tv, Azubu, and YouTube Gaming. Dreamhack Winter 2011 reached 1.7 million unique viewers on Twitch. While coverage of live events usually brings in the largest viewership counts, the recent popularization of streaming services has allowed individuals to broadcast their own gameplay independent of such events as well. Individual broadcasters can enter an agreement with Twitch or Hitbox in which they receive a portion of the advertisement revenue from commercials which run on the stream they create.
Another major streaming platform was Major League Gaming's MLG.tv. The network, which specializes in Call of Duty content but hosts a range of gaming titles, has seen increasing popularity, with 1376% growth in MLG.tv viewership in Q1 of 2014. The 2014 Call of Duty: Ghosts broadcast at MLG's X Games event drew over 160,000 unique viewers. The network, like Twitch, allows users to broadcast themselves playing games, though only select individuals can use the service. For several years, MLG.tv was the primary streaming platform for the Call of Duty professional scene; famous players such as NaDeSHoT and Scump have signed contracts with the company to use its streaming service exclusively. In January 2016, MLG was acquired by Activision Blizzard.
YouTube also relaunched its livestreaming platform with a renewed focus on live gaming and esports specifically. For The International 2014, coverage was also simulcast on ESPN's streaming service ESPN3. In December 2016, Riot Games announced a deal with MLB Advanced Media's technology division BAM Tech for the company to distribute and monetize broadcasts of League of Legends events through 2023. BAM Tech will pay Riot at least $300 million per-year, and split advertising revenue.
Especially since the popularization of streaming in esports, organizations no longer prioritize television coverage, preferring online streaming websites such as Twitch. Ongamenet continues to broadcast as an esports channel in South Korea, but MBCGame was taken off the air in 2012. Riot Games' Dustin Beck stated that "TV's not a priority or a goal", and DreamHack's Tomas Hermansson said "esports have [been proven] to be successful on internet streaming [services]."
On the night before the finals of The International 2014 in August, ESPN3 broadcast a half-hour special profiling the tournament. In 2015, ESPN2 broadcast Heroes of the Dorm, the grand finals of the Heroes of the Storm collegiate tournament. The first-place team from the University of California, Berkeley received tuition for each of the team's players, paid for by Blizzard and Tespa. The top four teams won gaming equipment and new computers. This was the first time an eSport had ever been broadcast on a major American television network. The broadcast was an attempt to broaden the appeal of esports by reaching viewers who would not normally come across it. However, the broadcast was met with a few complaints. Those living outside of the United States were unable to view the tournament. Additionally, the tournament could not be viewed online via streams, cutting off a large portion of viewers from the main demographic in the process.
In September 2015, Turner Broadcasting partnered with WME/IMG. In December 2015, the partnered companies announced two seasons of the ELeague, a Counter-Strike: Global Offensive league based in North America including 15 teams from across the world competing for a $1,200,000 prize pool each 10-week season. The tournament, filmed at Turner's studios in Atlanta, Georgia, is simultaneously streamed on online streaming websites and TBS on Friday nights.
In January 2016, Activision Blizzard, publishers of the Call of Duty and StarCraft series, acquired Major League Gaming. In an interview with The New York Times about the purchase, Activision Blizzard CEO Robert Kotick explained that the company was aspiring to create a U.S. cable network devoted to esports, which he described as "the ESPN of video games". He felt that higher quality productions, more in line with those of traditional sports telecasts, could help to broaden the appeal of esports to advertisers. Activision Blizzard had hired former ESPN and NFL Network executive Steve Bornstein to be CEO of the company's esports division.
TV 2, the largest private television broadcaster in Norway, broadcasts esports across the country. TV 2 partnered with local Norwegian organization House of Nerds to bring a full season of esports competition with an initial lineup of Counter-Strike: Global Offensive, League of Legends, and StarCraft II.
In April 2016, Big Ten Network announced a collaboration with Riot to hold an invitational League of Legends competition between two universities from the collegiate Big Ten Conference, as part of Riot's collegiate championships at PAX East. On 17 January 2017, Big Ten Network and Riot announced that it would hold a larger season of conference competition involving 10 Big Ten schools.
Nielsen Holdings, a global information company known for tracking viewership for television and other media, announced in August 2017 that it would launch Nielsen esports, a division devoted to providing similar viewership and other consumer research data around esports, forming an advisory board with members from ESL, Activision Blizzard, Twitch, YouTube, ESPN, and FIFA to help determine how to track and monitor audience sizes for eSport events.
In July 2018, on the first day of the inaugural 2018 Overwatch League season playoffs, Blizzard and Disney announced a multi-year deal that gave Disney and its networks ESPN and ABC broadcast rights to the Overwatch League and Overwatch World Cup, starting with the playoffs and continuing with future events.
