  The Battle.net World Championship Series (BWCS) was the shared branding for video game tournaments held by Blizzard Entertainment for their games StarCraft II (SC2) and World of Warcraft (WoW) in 2012. The StarCraft II event series, the StarCraft II World Championship Series, maintained the World Championship Series branding beyond the year and continued to use it until being replaced by the ESL Pro Tour StarCraft II in 2020, but the Battle.net World Championship Series brand was not used beyond 2012.
