Tyler "Ninja" Blevins, who recently teamed up with Drake to destroy Twitch's concurrent viewer record, confirmed in an interview with CNBC today that he earns roughly $500,00 per month—that's right, per month—as a streamer. Blevins said that much of those revenues come from Amazon and Twitch Prime subscribers, as well as a massive number of followers on YouTube, Instagram, and Twitter. 

"The combination of all those things is really where the collected revenues is coming from. This deal that Amazon Prime and Twitch Prime have together is incredible. Twitch Prime allows people to claim loot and collect loot with specific games, and they recently did a deal with Fortnite, which is the hottest game right now, and that is actually one of the main reasons of influx of subscribers to my stream."
