Eminence of/by the Chinese people
(traditional Chinese: 華人之碩; simplified Chinese: 华人之硕)
Asus is the world's 4th-largest PC vendor by 2015 unit sales. Asus appears in BusinessWeek’s "InfoTech 100" and "Asia’s Top 10 IT Companies" rankings, and it ranked first in the IT Hardware category of the 2008 Taiwan Top 10 Global Brands survey with a total brand value of $1.3 billion.
The company is usually referred to as "Asus" or Huáshuò in Chinese (traditional Chinese: 華碩; simplified Chinese: 华硕, literally "Eminence of/by the Chinese [people]"). According to the company website, the name Asus originates from Pegasus, the winged horse of Greek mythology. Only the last four letters of the word were used in order to give the name a high position in alphabetical listings. The company's slogan/tagline was "Rock Solid. Heart Touching", then "Inspiring Innovation. Persistent Perfection." Currently it is "In Search of Incredible."
- Rock Solid. Heart Touching (2003–2009)
- Inspiring Innovation. Persistent Perfection (2009–2013)
- In Search of Incredible (2014–present)
Asus was founded in Taipei in 1989 by T.H. Tung, Ted Hsu, Wayne Hsieh and M.T. Liao, all four having previously worked at Acer as hardware engineers. At this time, Taiwan had yet to establish a leading position in the computer-hardware business. Intel Corporation would supply any new processors to more established companies like IBM first, and Taiwanese companies would have to wait for approximately six months after IBM received their engineering prototypes. According to the legend, the company created a prototype for a motherboard using an Intel 486, but it had to do so without access to the actual processor. When Asus approached Intel to request a processor to test it, Intel itself had a problem with their motherboard. Asus solved Intel's problem and it turned out that Asus' own motherboard worked correctly without the need for further modification. Since then, Asus was receiving Intel engineering samples ahead of its competitors.
In September 2005 Asus released the first PhysX accelerator card. In December 2005 Asus entered the LCD TV market with the TLW32001 model. In January 2006 ASUS announced that it would cooperate with Lamborghini to develop the VX series.
On 9 March 2006 Asus was confirmed as one of the manufacturers of the first Microsoft Origami models, together with Samsung and Founder Technology. On 8 August 2006 Asus announced a joint venture with Gigabyte Technology. On 5 June 2007 Asus announced the launch of the Eee PC at COMPUTEX Taipei. On 9 September 2007 Asus indicated support for Blu-ray, announcing the release of a BD-ROM/DVD writer PC drive, BC-1205PT. ASUS subsequently released several Blu-ray based notebooks.
In January 2008, Asus began a major restructuring of its operations, splitting into three independent companies: Asus (focused on applied first-party branded computers and electronics); Pegatron (focused on OEM manufacturing of motherboards and components); and Unihan Corporation (focused on non-PC manufacturing such as cases and molding). In the process of the restructuring, a highly criticized pension-plan restructuring effectively zeroed out the existing pension balances. The company paid out all contributions previously made by employees.
On 9 December 2008, the Open Handset Alliance announced that Asus had become one of 14 new members of the organization. These "new members will either deploy compatible Android devices, contribute significant code to the Android Open Source Project, or support the ecosystem through products and services that will accelerate the availability of Android-based devices."
In October 2010, Asus and Garmin announced that they would be ending their smartphone partnership as a result of Garmin deciding to exit the product category. The two companies had produced six Garmin-ASUS branded smartphones over the prior two years.
In December 2010, Asus launched the world's thinnest notebook, the Asus U36, with Intel processor voltage standard (not low voltage) Intel core i3 or i5 with a thickness of only 19 mm.
As of 2009[update] Asus had manufacturing facilities in Taiwan (Taipei, Luzhu, Nangan, Guishan), mainland China (Suzhou, Chongqing), Mexico (Ciudad Juárez) and the Czech Republic (Ostrava). The Asus Hi-Tech Park, located in Suzhou, covers 540,000 m2 (5,800,000 sq ft).
Asus operates around 50 service sites across 32 countries and has over 400 service partners worldwide.
Asus' products include 2-in-1s, laptops, tablet computers, desktop computers, mobile phones, personal digital assistants (PDAs), servers, computer monitors, motherboards, graphics cards, sound cards, DVD disc drives, computer networking devices, computer cases, computer components and computer cooling systems.
One of Asus main lineup is the Vivo lineup consisting of laptops (VivoBooks), All-in-Ones (Vivo AiO), desktops (VivoPC), Stick PCs (VivoStick), Mini PCs (VivoMini), smartwatches (VivoWatch), computer mouse (VivoMouse) and tablets (VivoTab).
Asus also launched many Android-based smartphones, predominantly with Intel rather than ARM processors and often with two sim slots. Asus is currently very influential in big mobile markets like India, China and other Asian countries. It is known as the ZenFone series. Prior to the ZenFone line, Asus has released feature phones such as the Asus v70 and smartphones running on Windows Mobile during the mid-2000s.

Digital media receiversEdit
Republic of Gamers (ROG)Edit
Republic of Gamers is a brand used by Asus since 2006, encompassing a range of computer hardware, personal computers, peripherals, and accessories oriented primarily toward PC gaming. The line includes both desktops and high-spec laptops such as the Asus ROG Crosshair V Formula-Z Motherboard or the Asus ROG G751JY-DH71 Laptop.
Asus released its first sound card, the Xonar DX, in February 2008. The Xonar DX was able to emulate the EAX 5.0 effects through the ASUS GX software while also supporting Open AL and DTS-connect. In July 2008 ASUS launched the Xonar D1, which offered largely similar features to the Xonar DX but connected to the motherboard through the PCI interface instead of the PCI-E x1 connection of the Xonar DX. ASUS then released the Xonar HDAV 1.3, which was the first solution enabling loss-less HD audio bit streaming to AV receivers.
In May 2009, Asus launched the Essence ST sound card, targeted at high-end audiophiles, and featuring 124db SNR rating and precision audio clock tuning. In the same month, Asus refreshed the HDAV family by releasing the HDAV 1.3 slim, a card targeted for HTPC users offering similar functionality to HDAV 1.3 but in a smaller form. During Computex 2010, ASUS introduced its Xonar Xense, an audio bundle composed of the Xense sound card and a special edition of the Sennheiser PC350 headset. In August 2010, ASUS released the Xonar DG sound card targeted at budget buyers and offering 5.1 surround sound support, 105db SNR rating, support for Dolby headphone and GX 2.5 support for emulating EAX 5.0 technology.
ASUS VivoPC lineEdit
Asus entered the box-PC market with the Vivo PC line in November 2013. ASUS VivoPCs come without a pre-installed Windows operating system.
On 23 October 2013 ASUS launched two models of VivoPCs in India. VivoPC was initially announced with Intel Celeron processor equipped VM40B model. But in India, the company released VivoPC along with a new model called VC60 which is equipped by Intel Core series processors.
In 2013, Asus released the MB168B, a USB 3.0-powered, portable external monitor. The base model shipped with a resolution of 1366x768, while the MB168B+ had a resolution of 1920x1080. At the time of its release, the MB168B+ was the only 1080p portable monitor. According to Asus, it is the "world’s slimmest and lightest USB monitor".
- ROG Swift PG348Q
- ROG Swift PG35VQ
In 2000, Asus launched Green ASUS, a company-wide sustainable computing initiative overseen by a steering committee led by Jonney Shih, the Chairman of Asus. According to the company, Asus pursues green policies in "Design, Procurement, Manufacturing, and Marketing."
In 2006, Asus obtained IECQ (IEC Quality Assessment System for Electronic Components) HSPM (Hazardous Substance Process Management) certification for its headquarters and for all of its manufacturing sites.
In 2007, Oekom Research, an independent research institute specialising in corporate responsibility assessment, recognized Asus as a "highly environmental friendly company" in the "Computers, Peripherals and Office Electronics Industry".
In October 2008, Asus received 11 Electronic Product Environmental Assessment Tool (EPEAT) Gold Awards for its products, including four of its N-Series notebooks, namely the N10, N20, N50 and N80. In the following month, it received EU Flower certification for the same N-Series notebooks at an award ceremony held in Prague. In December 2008, Det Norske Veritas conferred the world’s first EuP (Energy-using Product) certification for portable notebooks on these machines.
In April 2008, Asus launched its "PC Recycling for a Brighter Future" program in collaboration with Intel and with Tsann Kuen Enterprise Co. The program collected more than 1,200 desktop computers, notebooks and CRT/LCD monitors, refurbished them and donated them to 122 elementary and junior high schools, five aboriginal communities and the Tzu Chi Stem Cell Center.
In September 2008, PC Pro discovered through a reader that Asus had accidentally shipped laptops that contained cracked and unlicensed software. Both physical machines and recovery CDs contained confidential documents from Microsoft and other organizations, internal Asus documents, and sensitive personal information including CVs.
At the time, an Asus spokesperson promised an investigation at "quite a high level", but declined to comment on how the files got on the machines and recovery media. It was demonstrated that an unattended installation of Windows Vista could accidentally copy material from a flash drive with a parameter in the "unattend.xml" file on the personal flash drive being used to script the installation.
On 23 February 2016, Asus settled a lawsuit filed by the American Federal Trade Commission. The lawsuit revealed the presence of critical security flaws in the company's home network routers, which put hundreds of thousands of consumers at risk. The insecure "cloud" services led to the compromise of thousands of consumers’ connected storage devices, exposing their sensitive personal information on the internet. The breaches took place during the course of Asus' marketing campaign which advertised its routers as including numerous security features that the company claimed could "protect computers from any unauthorized access, hacking, and virus attacks".
