Sega

SEGA is a company founded in Honolulu in 1940 to provide coin-op amusements for the American military station there. In 1965, SEGA merged with Rosen Enterprises, a photo booth company. Within a year, they started selling their first arcade game, Periscope.

Their business continued as they produced arcades. Eventually, they got into the console business with the SG-1000 and the SEGA Master System.

However, SEGA really started competing with Nintendo with the SEGA Genesis. They mounted an anti-Nintendo marketing campaign with the slogan "Genesis does what Nintendon't." They also advertised their Blast Processing, and competed game-wise as well, creating the world-famous Sonic the Hedgehog series.

However, their next system, the Saturn didn't sell as well. After the Dreamcast failed to sell well enough, they decided to leave the console business and focus even more on game development.

SEGA now publishes games on the Wii, Xbox 360, and the Playstation 3, as well as the Nintendo DS. SEGA is also publishing Genesis games on the Virtual Console.

Sega Master System
Sega first entered the video game console market in 1986 with the Sega Master System. The Sega Master system competed against the NES and the japanese master system competed against the Famicom.

Genesis
Eventually Sega realised that their master system console wasn't as good as the NES so shortly afterwards they created the Genesis/CD Drive with a release date of 1988. In 1991 Nintendo tumbled over with their Super Nintendo. The Genesis now features a todays controller.

Saturn
Sega started the making of the Sega Saturn and released it in 1993. Nintendo soon followed with their Nintendo 64 and Sony entered the market with the PlayStation.

Dreamcast
The Dreamcast started the 6th generation video console market with the Dreamcast. Sony soon followed up with their PlayStation 2 which actually was so good, it got sega out of the market forever. Microsoft and Nintendo soon followed with the Xbox and GameCube realising that Sega is out of the market.
