The livestreaming industry continues to mesmerize millions of viewers and this year Twitch, the preeminent gaming livestreaming service launched by Justin.tv in 2011 and bought by Amazon in 2014.

Over the years, Twitch has become one of the most-watched platforms for livestreaming but has started to see increased competition from Google’s YouTube livestreaming service and the recently launched Hitbox.

Today, Twitch distributed an infographic displaying some numbers generated from the Electronic Entertainment Expo trade show this year in Los Angeles. The graphic brags Twitch’s ever increasing viewership dominance with a 175 percent year-over-year increase in unique viewers—to 21 million viewers–and a 442 percent rise over last year in peak concurrent users—to 840 thousand or 16x more than the physical E3 attendees in LA.

According to the infographic, those 21 million users consumed almost 12 million hours of E3 content.

Twitch was sure to tout the introduction of co-streaming on the platform. For E3, Twitch streamers were permitted to re-stream content from the official Twitch E3 channel and re-brand the content with their own commentary. Of the total E3 viewership, 35 percent came from 1,801 unique Twitch channels, including SiliconANGLE, which participated in the co-streaming event.

Finally, Twitch also announced that the streaming service helped raise over $390,000 for charity with more than 174,000 E3 Digital Tickets sold through Humble Bundle.
