Conferences
From its inaugural season in 1895 until 1914, Oklahoma played as independent. In 1915, it became a charter member of the Southwest Conference. In 1920, it transferred to the Missouri Valley Intercollegiate Athletic Association. Oklahoma has remained with this conference through its various name changes (Big Six 1929, Big Seven 1948, Big Eight 1959, Big Twelve 1996) until the present day.
