"The Electronic Entertainment Expo, commonly known as E3, is an annual trade fair for the video game industry presented by the Entertainment Software Association (ESA). It is used by many video game publishers and accessory manufacturers to introduce and advertise upcoming games and game-related merchandise. Unlike Gamescom and other video-game trade fairs open to the public, E3 is an industry-only event; individuals who wish to attend are required by the ESA to verify a professional connection to the video-game industry.
E3 is usually held in late May or early June at the Los Angeles Convention Center (LACC) in Los Angeles; the most recent event was held from June 14–16, 2016. The show in 2017 will be held from June 13–15, 2017." - Wikipedia
