Microsoft no longer sells new movies and TV content and there is no indication in the provided information that this strategy will change or that a rebrand is planned.
According to the Movies & TV app guidance, Microsoft has stopped selling new movies and TV shows on Microsoft.com, Microsoft Store on Windows, and Microsoft Store on Xbox. Existing purchases remain playable through the Movies & TV app on Xbox and Windows devices, including previously downloaded content, but new transactional video sales are not being offered and purchased content cannot be moved to another service.
Because the current model is “no new sales, playback only for existing purchases,” a rebrand to “Xbox Video” and a renewed transactional store (including Movies Anywhere-style integration) would require a reversal of this stated policy, which is not reflected anywhere in the available documentation.
Users who want to buy new movies and TV are instead directed to other services available on Xbox and Windows, such as Amazon Prime Video, Apple TV, and Fandango at Home.
