E3 Expo or Entertainment Expo is held in Santa Monica, California from July 11 to July 13. As of 2007, E3 will be invitation-only, meaning that instead of tens of thousands of people at E3 there will only be few thousands people attending. The change is done to give E3 more emphasize on business. To cater for the public, there’s also a separate conference called Entertainment for All Expo – an annual video game event. GameSpot is also covering E3, so you might want to check out their site too to get insight on what going on in the gaming business.
