The College Football Playoff National Championship is a postseason college football bowl game, used to determine a national champion of the NCAA Division I Football Bowl Subdivision (FBS), which began play in the 2014 college football season. The game is held on a Monday in mid-January and serves as the final game of the College Football Playoff (CFP), a bracket tournament between the top five ranked conference champions, and the top 7 ranked at-large teams in the country that are selected by a playoff committee, which was established as a successor to the Bowl Championship Series and then its similar BCS National Championship Game.
