ATI

ATI Technologies Inc. (where ATI is an acronym for Allied Telesyn International) is a Canadian manufacturer of graphics cards and graphics chips and graphics processing units for personal computers, founded in 1985.
It began as an OEM, producing integrated graphics chips for large PC manufacturers like IBM. However, by the mid '90s it had evolved into an independent graphics card retailer, marketing the ATI Rage 128 series under its own ATI moniker.
In addition to developing high-end GPU's (graphics processing unit, something ATI themselves call VPU for visual processing unit) for PCs, ATI also designs "lite" versions for laptops, PDAss, set-top boxes and other technology-based market segments.
In 2000, ATI acquired the company ArtX that engineered the graphics chip "Flipper" used in Nintendo GameCube. They have also entered an agreement with Nintendo to create the chip for the next generation of GameCube. ATI are now working with Microsoft to create the graphics chip for Microsoft Xbox 2.
Currently it is the main competitor of nVidia, whom also produces graphics cards. As of 2004, ATI's flagship product line is the Radeon series of graphics cards which directly compete with nVidia's GeForce graphics cards.
Market Trends
For the past several years the GPU market has largely followed a pattern whereby ATI releases a new product and controls the performance market but only for a short period of time. nVidia (or ATI depending on who releases what first) then releases its counter product and thereupon controls the performance market for yet another short period of time, ad infinitum.
In 2003, ATI launched a program called "get in the game" to help game developers optimize their applications for ATI's hardware. NVIDIA's version is called "the way it's meant to be played".
