The Championship Manager is a series of British football-management simulation computer games, the first of which was released in 1992. The Championship Manager brand and game was conceived by two brothers: Paul and Oliver Collyer. In a scenario typical of many self-made computer game programming teams in the early days of the industry, the original Championship Manager game was written from their bedroom in Shropshire, England. The brothers subsequently founded a development company to take the game further, Sports Interactive, and moved to Islington, North London. Championship Manager became the most popular football management sim of the later 1990s and early 2000s, regularly setting sales records.
