Football Manager, also known as Worldwide Soccer Manager in North America from 2004 to 2008, is a series of football management simulation video games developed by British developer Sports Interactive and published by Sega. The game began its life in 1992 as Championship Manager. Following the break-up of their partnership with original publishers Eidos Interactive, triggered by the fiasco release of Championship Manager 4 in 2003, Sports Interactive lost the naming rights to Eidos Interactive but retained the game engine and data, and re-branded the game Football Manager with their new publisher Sega. The latest version of Football Manager, titled Football Manager 2024, was released on 7 December 2023. Football Manager 2024 is the most played title in series history, clocking 7 million players by the end of February 2024. Football Manager 25, originally intended for a November 2024 release, was cancelled in February 2025 after multiple delays.
