SEGA, a brief background

Sega (which is a contraction for "Service Games") was founded in 1951 as Rosen Enterprises, as an art export company. It was founded by David Rosen, an American businessman. The company's name was changed from Rosen Enterprises to Sega in 1965 when Rosen merged with a jukebox manufacturing company.

During the 1970's, Sega produced arcade games and expanded into console software for the Atari 2600 and ColecoVision during the early '80s. Several very successful products, such as Turbo (which was packaged with ColecoVision's driving controller), as well as the products Frogger and Zaxxon prompted corporate changes and the selection of a new name: Sega Enterprises, Ltd.

Sega produced the Sega Master gaming console in the mid 1980's, after Nintendo's success with its NES machine. For a variety of reasons, Sega was unable to gain sufficient market control with this product, and so it was discontinued.

In 1989, Sega introduced the 16-bit Sega Genesis. It enjoyed success and had great popular games and strong third-party support.

In 1995, Sega introduced the Sega Saturn with great conversions of popular Sega arcade games and the NetLink adapter, which made it one of the first internet-ready consoles. However, Sony's Playstation eventually took over the market lead position in this area.

In 1999, Sega introduced Dreamcast, and sold 500,000 units in the first two months. Dreamcast became the fastest selling games console on the market.

In April 2000,, Inc. was introduced as a new, independent, online Internet entertainment company.'s stated goal is to become the online destination for gamers. (See their web site at
