d20 isn't so much a game system as a framework upon which other game systems are built. It was released by Wizards of the Coast under an "open source" type license known as the OGL - Open Gaming License (RTF). This essentially allows 3rd party companies to use the core rules as a foundation when building their own games or when publishing compatible materials for other d20/OGL games.
Numerous games have been built on the d20 framework, with WotC's own Dungeons and Dragons 3rd Edition (3.5) being the most popular. Other major d20 systems include d20 Modern and Star Wars d20.
d20 has also been used in rewrites of lots of older games including Call of Cthulu and the old AD&D Ravenloft campaign setting.
