Note: The Pac-12 Conference was known by the following names in its pre-2011 history:
 * Athletic Association of Western Universities (AAWU) – Official name from the conference's formation in 1959 to June 1968.
 * Big Five – Unofficial name beginning in 1959. Used until Washington State joined in July 1962.
 * Big Six – Unofficial name beginning in July 1962. Used until Oregon and Oregon State joined in July 1964.
 * Pacific-8 Conference – Unofficial name beginning in July 1964; officially adopted in July 1968. Used until Arizona and Arizona State joined in July 1978.
 * Pacific-10 Conference – July 1978 to June 2011.

Also, although the Pacific Coast Conference (PCC) operated under a separate charter from its establishment in December 1915 until its dissolution in 1959, the Pac-12 claims the PCC's history as its own. By July 1964, eight of the final nine PCC members had reunited in the AAWU/Pac-8.

All categories from 2010–11 and earlier should reflect the name used in that period.
