We have reported many times that the new Apple TV is getting an App Store. The new A8-powered box combined with a revamped software interface will enable developers to make apps and games for the new hardware, set to be announced at tomorrow’s iPhone 6S/Apple TV/iPad event. TechCrunch is reporting, via sources, that Periscope, the video live streaming app for iPhone and Android, is working with Apple in advance of the unveiling to create a custom Periscope app for the new Apple TV.

Although we can’t confirm the report, it does seem like a natural fit for a TV app. Akin to a live YouTube, you can imagine users opening Periscope on the Apple TV and browsing live streams from users. Periscope is also owned by Twitter, a company known to have a close relationship to Apple. This makes it a logical fit for Apple to partner with ahead of the announcement. Unfortunately, the TechCrunch piece is lacking in detail but there is a chance we could see Periscope demoed on stage tomorrow. Apple will want to evangelize the Apple TV platform to developers as well as advertising to customers, so some number of app demos for the Apple TV 4 are almost a given. We would expect Apple to show off at least one demo of a game running on the new hardware as well.

Apple’s Hey Siri event starts at 10 AM PT tomorrow. The event will feature the announcement of the new iPhone 6S / iPhone 6S Plus, new iPads, Apple Watch accessories, iOS 9 details as well as the unveiling of the brand new Apple TV product. Read all about the event in our roundup.
