The AAWU eventually strengthened its bonds and added members, renaming itself the Pacific-8 Conference (Pac-8) in 1968. By 1971, most Pac-8 schools played round-robin conference football schedules, and the two Oregon schools were again playing USC and UCLA on a regular basis. The conference added WAC powers Arizona and Arizona State in 1978 and became the Pacific-10 Conference (Pac-10). On July 1, 2011, the conference added Colorado from the Big 12 and Utah from the Mountain West (also a former WAC member) and became the Pac-12. The Pac-12 claims the PCC's history as its own, though it operates under a separate charter.
