This year's E3 conference saw 48,200 attendees from 102 countries, a 5.5 per cent increase on 2012's 45,700.
"This year's E3 showcased the best that our industry has to offer and channelled the immense energy, drive, and enthusiasm for video games onto a global stage," said ESA CEO Michael D. Gallagher.
"Thanks to our members and exhibitors' boundless capacity for innovation, billions of consumers are seeing the future of our industry through this outstanding landscape of creativity, technology and content."
