The Cyberathlete Professional League (CPL) was a professional sports tournament organization specializing in computer and console video game competitions. It was established by Angel Munoz on June 27, 1997, hosting biannual tournaments in hotels. The CPL's World Tour in 2005 marked a global expansion of esports, but concerns arose about fan engagement and attracting new audiences. The post-tour era saw increased competition from the WSVG, and the CPL faced financial troubles including the loss of its main sponsor, Intel, to WSVG in 2006. Shortly after, WSVG's Matt Ringel purchased the 2006 CPL Summer event, leading to a decline in the CPL's influence. The CPL attempted a "World Season" in late 2006, hosting fewer events with reduced prize money. Rumors circulated about the league's health, and in March 2008, the CPL ceased operations. Later that year, the CPL was acquired by an investment group in Abu Dhabi, later becoming solely owned by WoLong Ventures PTE of Singapore. The CPL continued hosting annual competitions in China in collaboration with the municipal government of Shenyang.
