Acclaim Entertainment was an American video game developer and publisher. It developed, published, marketed and distributed interactive entertainment software for a variety of hardware platforms, including Sega's Mega Drive/Genesis, Saturn, Dreamcast, and Game Gear, Nintendo's NES, SNES, Nintendo 64, GameCube, Game Boy, Game Boy Color, and Game Boy Advance, Sony's PlayStation and PlayStation 2, Microsoft's Xbox, and, to a lesser extent, personal computer systems and arcade games. It also released video games for the Sega Master System in Europe.
Since Acclaim Entertainment's 2004 demise, the Acclaim brand and logotype have been purchased by Acclaim Games and are now used by this unrelated company. Canadian video game publisher Throwback Entertainment acquired 150+ titles of Acclaim's video game library.
