ESL, originally named the Electronic Sports League, is a company that organizes esports events on a global scale. It is currently the world’s largest esports company, based in Cologne, Germany, and holds 11 offices as well as multiple international TV studios.
The ESL launched in 2000 and started with an online gaming league and magazine. For more revenue, it also rented out servers for game competitions, and the production more than doubled from 2012 to 2014. ESL runs events mainly for Counter Strike: Global Offensive and Dota 2 but also hosts events of other games like League of Legends and StarCraft 2. ESL also hosts a number of events for a range of skill sets.
In 2017, ESL One LAN events will take place in Cologne (Counter-Strike, July 7-9), New York (Counter-Strike, Sept. 16-17) and Hamburg, Germany (Dota 2, Oct. 27-28).
