This article covers the period from 1877 to present. Before the beginning of the Open Era
in April 1968, only amateurs
were allowed to compete in established tennis
tournaments, including the four Grand Slam
tournaments (also known as the majors). Wimbledon
, the oldest of the majors, was founded in 1877, followed by the US Open
in 1881, the French Open
in 1891 and the Australian Open
in 1905. Beginning in 1905 and continuing to the present day, all four majors have been played yearly, with the exception of during the two World Wars, 1986 for the Australian Open, and 2020 for Wimbledon
. The Australian Open is the first major of the year (January), followed by the French Open (May–June), Wimbledon (June–July) and the US Open (August–September). There was no prize money and players were compensated for travel expenses only. A player who wins all four majors, in singles or as part of a doubles team, in the same calendar year is said to have achieved a "Grand Slam". If the player wins all four consecutively, but not in the same calendar year, it is called a "Non-Calendar Year Grand Slam". Winning all four at some point in a career, even if not consecutively, is referred to as a "Career Grand Slam". Winning the four majors and a gold medal in tennis at the Summer Olympics in the same calendar year has been called a "Golden Slam" since 1988. Winning all four majors plus an Olympic gold at some point in a career, even if not consecutively, is referred to as a "Career Golden Slam". Winning the year-end championship
while also having won a Golden Slam is referred to as a "Super Slam". Winning all four majors, an Olympic gold, and the year-end championships at some point in a career, even if not consecutively, is referred to as a "Career Super Slam". Winning the four majors in all three disciplines a player is eligible for–singles, doubles and mixed doubles–is considered winning a "boxed set" of Grand Slam titles.
Prior to 1924, the major tennis championships, governed by the International Lawn Tennis Federation (ILTF), were the World Hard Court Championships
, World Grass Court Championships (Wimbledon), and World Covered Court Championships
