The biggest Counter-Strike: Global Offensive (CS:GO) event in the world so far, took place in Cologne last weekend. Alongside the European and US teams, that competed for 250.000 USD, the prize money also attracted 11.000 viewers a day. The event was held in the LANXESS Arena, Germany’s largest indoor arena.

Even more viewers were watching the tournament on their screens at home, counted 27 million unique viewers in total.

Concerning CS:GO, the bar for future events has been raised, as the event -organized by the Electronic Sports League (ESL)- has met all expectations. In addition to the viewers on the streaming website, 27 million unique viewers have watched the tournament. Last year’s major event, the League of Legends world cup, attracted up to 32 million viewers, and the ESL One is catching up.
