In 2009, there were 21,547 PC Bangs [Internet cafes] in Korea, which were the major contributor for Korea to become the world leader in professional online gaming. But in 2010, the number declined to 19,014, and in 2011 the number further declined to 15,817--according to this Dong-A Ilbo article.
Oversupply, faster wi-fi and competing entertainment venues such as coffee shops (whose number and quality vastly improved in the last five years) are blamed for PC Bangs' decline. The article notes that online game companies such as Riot Games, Blizzard and Nexon are working together with PC Bangs to help their survival, so that they may continue to serve as an outlet for their games.
