E3 2021

The Electronic Entertainment Experience 2021 (E3 2021) was the 26th and final E3, during which hardware manufacturers, software developers, and publishers from the video game industry presented new and upcoming products. The event, organized by the Entertainment Software Association (ESA), ran as a virtual, online-only event with free access to all, from June 12–15, 2021.

Virtual events included keynote sessions from major publishers broadcast from a live stage in Los Angeles, an awards show, and a preview night, as well as helping companies to hold online private meetings with media and businesses. Because of the online-only nature, the event had been rebranded for the year as the Electronic Entertainment Experience rather than the standard Electronic Entertainment Expo. Greg Miller, Jacki Jing, and Alex "Goldenboy" Mendez served as hosts of the virtual events.

E3 2021 followed the cancelled E3 2020 event due to the COVID-19 pandemic and after the ESA could not work out a replacement event in time. The ESA had intended to hold an in person event in 2021 during its normal June dates, as stated to partners in April 2020, but had to alter their plans due to ongoing COVID-19 concerns. E3 2021 was free for everyone to attend. While the 2021 event was entirely online, ESA planned to return to an in-person event by 2022, though these plans were scrapped and the in-person event was cancelled in January 2022, and E3 2022 was cancelled altogether on March 31, 2022, including the digital event. In July 2022, it was confirmed that E3 2023 would mark a return to the in-person event. However, the lack of interest and attendance of major publishers caused the event to be cancelled as well, leading to the announcement of the event's complete defunction in December 2023.

Companies that participated at the event included Nintendo, Microsoft, Capcom, Ubisoft, Take-Two Interactive, Warner Bros. Interactive Entertainment, Koch Media, Square Enix, Sega, Gearbox Software, Bandai Namco Entertainment, Turtle Beach, Verizon, and Xseed Games. Konami had planned to participate but announced later they would not be ready to present at E3 as they were deep into development on several projects which they would reveal at a later time.
