There are still some missing apps, however. One of those apps is Movies & TV, which is only available on Windows-based platforms like Windows 10 PC, Xbox, and Windows 10 Mobile. If you're a movie buff with a large collection from Microsoft's store, the lack of an iOS or Android app is unfortunate. It's also likely a barrier for any potential new customers looking to buy movies or TV content. But it appears Microsoft is now finally working on bringing its Movies & TV service to iOS or Android, according to sources familiar with the matter.
My sources suggest Microsoft is building these apps to give consumers more of a reason to buy content in the Microsoft Store. While most people have moved over to streaming content via services like Netflix, there is still a whole lot of content that isn't immediately, or ever, available to stream. Lots of people buy digital movies and TV content, and Microsoft has a huge store that a lot of people seemingly ignore or don't know about because there is no mobile companion app for their phone.
These apps should minimize that barrier for a lot of people and further solidify Microsoft's commitment to its digital offerings on the Microsoft Store. Last year, Microsoft killed its music-streaming service, which saw many people question whether Microsoft was going to do the same to its Movies & TV service. Microsoft says that it continues to remain committed to Movies & TV, however (mostly because of Xbox), and these new mobile apps should help with that message.
