The Xbox is the first home video game console created by Microsoft.With Sega having to drop out of the video game hardware business due to half a decade of declining revenue, chairman Isao Okawa met with Microsoft owner Bill Gates, who was looking to get into the video game industry, to discuss a merger of video game divisions, or even buying Sega outright but talks broke down and failed due to Bill Gates not believing Sega had the muscle to eventually stop Sony.
Despite this, a business alliance was made with Microsoft, with Sega agreeing to develop 11 games for their brand new console.
