E3 2015 - Attendance at E3 this year saw over 50,000 attendees, which is a first since 2006. Attendance numbers slumped in 2007 and 2008, right down to less than 6,000 - but don't worry, things started swinging up in 2009 right up to over 40,000.
The Entertainment Software Association, the people behind E3, has already announced that E3 2016 will take place between June 14 and 16 in 2016, as well as saying that this year's E3 was a record-breaker. Twitch was the official livestreaming partner of E3 this year, with over 500,000 peak concurrent viewers.
274 exhibitors were at E3 this year, up from just 187 in 2015, too.
