During its beta phase in the early 2010s, several other esport events would begin hosting "Dota 2" events, including the Electronic Sports World Cup, DreamHack, World Cyber Games, and ESL. By the end of 2011, "Dota 2" was already one of the highest-paying esport games, second only to "StarCraft II". At E3 2013, South Korean company Nexon announced the investment of 2 billion (approximately 1.7 million) into local leagues in the country, which coincided with their distribution partnership with Valve for the game. In February 2015, Valve sponsored "Dota 2" Asia Championships was held in Shanghai with a prize pool of over $3 million, raised through compendium sales. Since then, other "Dota 2" Asia Championships have taken place, with it being sometimes being referred to as the "Chinese International". In total, professional "Dota 2" tournaments had earned teams and players over $100 million by June 2017, with over half of that being awarded at Internationals, making it the highest earning esport game by a margin of nearly $60 million at the time.
