Champions by year
The following teams have been designated as champions by the conference.

† The NCAA sanctioned USC in June, 2010 for violations in the football, men's basketball, and women's tennis programs. USC football vacated two wins from their final two games of the 2004 season (one conference game and a bowl game) and all 12 wins from the 2005 season, as well as the conference titles from both years. Their 2004 BCS National Championship was vacated, while their 2004 Associated Press title was not removed.

‡ California claims five national titles that are based upon one contemporary "major selector" (Dick Dunkel in 1937) and seven retrospective selectors listed in the NCAA Football Bowl Subdivision Records (five of the eight selectors being math systems).

§ Stanford was selected in 1926 by a contemporary “major selector” (Frank Dickinson) and later by three retrospective selectors (two of the four being math systems).

@ USC claims national titles in 1931 and 1932 that are based upon four contemporary “major selectors” (William Boand, Frank Dickinson, Dick Dunkel, and Deke Houlgate) and nine later retrospective selectors (nine of the 13 selectors being math systems).
