There are, it seems to me, to be two essentially disparate audiences. 1] Likes watching game A. 2] Likes watching streamer K The first group choose the game, and then the streamer who is online and most enjoyable to watch playing it. The second choose the streamer and will watch whatever they're doing. Arguably the advantage that the variety streamers have is that pro games don't eat into their viewers. I'll watch arteezy play dota whilst cookin or something, but only if there's no proper matches on with teams I like. I suspect that SingSing will always have a few thousand viewers because his followers are passionate about watching him.
