Twitch viewers live-streamed 2.72+ billion hours in Q2, that is 72% of all live hours watched. The closest rival Twitch has is Youtube Live at 19%.
So what are people watching on Twitch? 75% viewership hours was spent watching individuals, specifically the top 5000 streamers on Twitch or the T5K. This small group of streamers is vital to Twitch's success.
E-sports makes up less than 25% of the viewership hours, but e-sports has become a great gateway for brands to reach the T5K and their massive audience.
