If the concept of watching other people play video games seems stupid, then you might want to look at the salaries top e-sport gamers are commanding.
Carlos Rodriguez Santiago, or Ocelote as he is known in the e-sports world, was one of the top players and biggest brands ever. He started his championship-winning career at age 16. He has now retired at the grand old age of 24, after earning around 700,000 euros ($773,108) a year playing games.
The e-sport tournaments involve teams playing each other in popular fantasy titles such as "League of Legends" or "World of Warcraft," while avid fans around the world watch over the Internet. Twitch, the company Amazon bought for $970 million, is the most popular live game-streaming website. It said that in July more than 55 million unique visitors viewed more than 15 billion minutes of content, highlighting how engaged users are with e-sports.
"The good thing is that we have hit mainstream already. It is not just guys playing video games, it's about the ecosystem around the audience and content generation," said Sebastien Radu, managing director of ESL Spain, a company that organizes some of the world's biggest e-sports tournaments. In an interview with CNBC at Mobile World Congress in Barcelona, Radu said some players could also earn more than $1 million.
