The NFL and Cosm Partner to Deliver Select Live NFL Games in Shared Reality
October 29, 2024
New partnership allows fans to experience live NFL action in a completely new way – through Shared Reality at Cosm’s venues in Los Angeles and Dallas
The NFL and Cosm, a leading immersive technology, media, and entertainment company, announced a partnership that will see Cosm produce and distribute
select NFL games at their venues throughout the 2024 regular season. Cosm delivers fans a new way to experience live NFL games through Shared Reality – an experience that bridges the virtual and physical worlds by merging state-of-the-art visuals with the energy of the crowd and an elevated food and beverage service.
Currently operating in Los Angeles (Hollywood Park) and Dallas (Grandscape), Cosm’s experiential venues feature large-scale 87-foot-diameter 12K+ LED domes, enabling fans to watch live NFL action in a completely new and different way. Going forward, Cosm’s venues will feature Thursday Night Football (Prime Video), Sunday Night Football (NBC), and Monday Night Football games, as well as select games on FOX, for the remainder of the 2024 NFL regular season.
