In 2003, Sports Interactive split with Eidos, the publishers of "Championship Manager". Sports Interactive retained the game's database and match engine, producing a new game based on these titled "Football Manager". Eidos retained the name and interface, with BGS taking over the development of "Championship Manager". Although the two series initially ran alongside one another, the sales of "Championship Manager" began to fall below those of "Football Manager". The most recent full version of Championship Manager was "Championship Manager 2010", with an iOS mobile game in 2011 the latest game to date released by Eidos.
