Madden NFL (known as John Madden Football until 1993) is an American football sports video game series developed by EA Tiburon for EA Sports. The franchise, named after Pro Football Hall of Fame coach and commentator John Madden, has sold more than 130 million copies as of 2018. Since 2004, it has been the only officially licensed National Football League (NFL) video game series, and has influenced many players and coaches of the physical sport. Among the series' features are detailed playbooks and player statistics and voice commentary in the style of a real NFL television broadcast. As of 2013 the franchise has generated over $4 billion in sales, making it one of the most profitable video game franchises on the market. Electronic Arts (EA) founder Trip Hawkins conceived the series and approached Madden in 1984 for his endorsement and expertise. Because of Madden's insistence that the game be as realistic as possible, the first version of John Madden Football did not appear until 1988. EA has released annual versions since 1990, and the series' name changed to Madden NFL in 1993 after EA acquired the rights to use NFL teams and players.
