Both Jesse and Brandon stream on Twitch, where money comes from fans that like their style. You need a balance of talent and personality -- fans come home after a day's work looking to unwind by watching some gaming, but if you don't offer something unique compared to the thousands of other young white guys doing the exact same thing, then they're going to look elsewhere.
"[Viewers will] thank you for streaming, or they'll pay you to try a strategy," explains Jesse. "A lot [of money] comes from subscriptions and players who are really interested in you, who want to throw money at you and say they love the entertainment you provide. I tell myself it's similar to a street performer who's got the hat on the ground."
Except pedestrians don't have the option to switch between 5,000
other people doing covers of "Wonderwall."
You're essentially marketing yourself like a less morally offensive Kardashian.
"I've seen people who have T-shirts, they do giveaways. I think some of the most famous streamers are the ones who sit back and give away most of the stuff the sponsors give them. There are a lot of ways to market; it's just about being creative."
You also need good timing, as the popularity of games can wax and wane. If you can get in on the ground floor of a hot new game, you'll be in a much stronger position than someone who's just now trying to become the next big Counter-Strike streamer. Then you just have to hope that everyone doesn't quickly lose interest in the game you've mastered.
