Has nothing to do with this...
has 100% to do with Summit1g, one of twitchs biggest streamers but was falling behind Ninja and Shroud (who he once was bigger than) during the Fortnite/PUBG era. He used to average 20-25k viewers but couldnt find his niche in the battle royal genre so he bounced from game to game while losing his usual viewership
he just picked up Sea oF thieves again the past 1-2 months and because it was different viewing experience from an established big streamer people flocked to it .. he used to average 12-15k viewers during this down spiral.. now he averages 50-70k viewers and now other popular streamers (TimTheTatMan and DrDisrespect) are playing the game more actively
Lightning in a bottle pretty much... went from 14k subs to 45k subs in a month
this is why game companies pay people like Summit, Shroud and Ninja $5-10,000 for 2 hours of game play on twitch if their viewership is around 10-20+k viewers because if even a fraction of those people watching buy the game theyll recoup the money in seconds..
hes streaming right now... he just turned on his stream like a hour ago.. already 40k viewers
