Summer Game Fest

Summer Game Fest is a live video game event organized and hosted by game journalist Geoff Keighley. The event takes place annually over multiple live streams during the North American summer period, the most notable of which is the "main show" which usually airs on the first day of the event and showcases upcoming major releases. The "main show" is usually then followed by multiple streams over the next few days from other publishers or groups, such as an Xbox Game Studios showcase or "Day of the Devs" featuring several indie games.

While Keighley had been involved in events associated with E3, one of the game industry's prominent events, he had expressed concern and dissatisfaction with the direction the Entertainment Software Association (ESA) had planned for the event in 2020, and withdrew from participation. When the COVID-19 pandemic caused the cancellation of physical events for E3 and Gamescom in 2020, Keighley established the streaming Summer Game Fest presentation to help replace these events. Following the ESA's decision to discontinue E3 after 2021, Summer Game Fest has become the default mid-year showcase for game announcements, and often is nicknamed as "not-E3" because of this substitution.
