Microsoft has announced that it will be closing down the Xbox 360 Store next year.
In a new post on the official Xbox Wire blog, it was announced that the ability to buy new games, DLC and other entertainment content from the Xbox 360 store will end on July 29, 2024.
This specifically refers to the ability to buy content directly through the Xbox 360 console, and the ability to buy content from the Xbox 360 Marketplace site.
It does not affect the ability to buy backwards compatible Xbox 360 games and DLC on the Xbox One or Xbox Series X/S stores, which will continue to be available.
