Global StarCraft II League
Both of Korea's individual leagues, Ongamenet's Ongamenet Starleague (OSL) and GOMTV's Global StarCraft II League (GSL), were included in this new WCS format in 2013. The leagues alternated, with the first and last seasons of WCS 2013 in Korea being GSL events, and the second being an OSL event. In 2014, all Korean leagues were GSL events as the OSL had officially ceased operations.
