The current conference champion is Arizona State, the school's first Big 12 title.
On July 27, 2023, Colorado, a former member of the Big 12, announced it would rejoin the conference from the Pac-12 beginning in the 2024–25 academic year.
From the time the league was formed until realignment, the conference was split into two, six team, divisions.
After the departure of Nebraska and Colorado, both the divisional format and the Championship Game were dropped.
[14] Since its inception in 1996, the Big 12 championship has been won by nine different schools, three of which no longer belong to the conference.
Following the departures of two schools in 2010, the conference discontinued the championship game in favor of a round-robin format to determine the champion.
Following the completion of the round-robin regular season, the conference's top two teams compete in the championship game.
Oklahoma defeated TCU 41–17 on December 2, 2017, in the first Big 12 Championship Game played since 2010.
