The Association of Volleyball Professionals (AVP) is the biggest and longest-running professional beach volleyball tour in the United States. Founded in 1983, the AVP is headquartered in Newport Beach, California. The AVP operates as a 3-tiered development system with AVPFirst, a youth program; AVPNext, a developmental circuit; and the tour itself. The sport experienced significant growth in the 1980s and 1990s, but was hit hard by the 2008 financial crisis which saw it lose sponsors and revenue.
