E3

E3 (short for Electronic Entertainment Expo) was an annual trade event for the video game industry organized and presented by the Entertainment Software Association (ESA). It was held principally in Los Angeles from 1995 to 2019, with its final iteration held virtually in 2021. The event hosted developers, publishers, hardware manufacturers, and other industry professionals who used the occasion to introduce and advertise upcoming games, hardware, and merchandise to the press. During its existence, E3 was the world's largest and most prestigious annual gaming expo.

E3 included an exhibition floor for developers, publishers, and manufacturers to showcase their titles and products for sale in the upcoming year. Before and during the event, publishers and hardware manufacturers usually held press conferences to announce new games and products. Before 2017, E3 was an industry-only event; the ESA required individuals wishing to attend to verify a professional relationship with the video game industry. With the rise of streaming media, several press conferences were broadcast to the public to increase their visibility. E3 2017 became open to the public for the first time, with 15,000 general-admittance passes for those who wanted to attend.

When hosted in Los Angeles, E3 was held in the Los Angeles Convention Center. The event was cancelled for the first time in 2020 due to the COVID-19 pandemic, and the event in 2021 was held as a virtual event to mixed reception. The 2022 event was cancelled also due to the pandemic, and with no virtual event held. The ESA had planned to return to a full in-person convention in 2023 with a new format, including a fan convention component at a separate venue in collaboration with ReedPop.

The pandemic further accelerated the use of standalone presentations by individual publishers and media outlets to promote upcoming games directly to consumers, development timelines usually aligned around the convention had been disrupted, and publishers were increasingly concerned over the costs of exhibiting at the convention. E3 2023 was cancelled after all major publishers pulled out of the event. E3 2024 was also cancelled in September 2023 in order to evaluate plans for 2025. However, on December 12, 2023, the ESA announced that the E3 would no longer be held.

Before E3, game publishers went to other trade shows like the Consumer Electronics Show and the European Computer Trade Show to display new or upcoming products as well as to pre-sell shipments to retailers for the rest of the year including the late-year holiday season as well as to view for press coverage of upcoming games. As the game industry grew rapidly during the early 1990s, industry professionals felt that it had outgrown the older trade shows. According to Tom Kalinske, CEO of Sega of America, "The CES organizers used to put the video game industry way, way in the back. In 1991, they put us in a tent, and you had to walk past all the porn vendors to find us. That particular year it was pouring rain, and the rain leaked right over our new Genesis system. I was just furious with the way CES treated the video game industry, and I felt we were a more important industry than they were giving us credit for." Sega did not return to CES the following year, and several other companies exited from further CES shows.

Separately, in 1994, the video game industry had formed the Interactive Digital Software Association (IDSA, later becoming the Entertainment Software Association, ESA, in 2003) in response to attention the industry had drawn from the United States Congress over a lack of a ratings system in late 1993. The IDSA was formed to unify the video game industry and establish a commission, the Entertainment Software Ratings Board (ESRB) to create a voluntary standard rating system that was approved by Congress.

The industry recognized that it needed some type of trade show for retailers. According to Eliot Minsker, chairman and CEO of Knowledge Industry Publications (which produced and promoted the show with Infotainment World), "Retailers have pointed to the need for an interpretive event that will help them make smarter buying decisions by interacting with a wide range of publishers, vendors, industry influentials, and opinion leaders in a focused show setting." Attempts were made between the video game companies and the Consumer Electronics Association (CEA) which ran CES, to improve how video games were treated at CES, but these negotiations failed to produce a result. Pat Ferrell, creator of GamePro which was owned by International Data Group (IDG), conceived of an idea for starting a dedicated trade show for video games, building off IDG's established experience in running the Macworld convention. Ferrell contacted the IDSA who saw the appeal of using their position in the industry to create a video game-specific tradeshow, and offered to co-found the Electronic Entertainment Expo with IDG.

Though several companies agreed to present at this E3 event, Ferrell discovered that CEA had offered video game companies a dedicated space at the next CES, which would have conflicted with the planned E3 event, requiring the companies to pick one or the other. Most of the IDSA members supported E3, while Nintendo and Microsoft were still supportive of the CES approach. After about three to four months, Ferrell was told by CEA's CEO Gary J. Shapiro that he had "won" and that they had canceled the CES video game event, effectively making E3 the premier trade show for the video game industry.
