This is seriously cool. Shocked at how well the panning/scrolling works using the Apple TV remote. Great work @bininunez and @hessotony

This is probably my favorite viewing experience for 360 video. It's social, I can sit around the living room with my family and friends and watch immersive content, it's on a big screen, and feels both natural and new. If you have a new Apple TV (or get one!), this is a must have app. We want consumers to be able to watch immersive content on any device: iOS, Android, the Web, VR headsets, and now their televisions.

So much fun using this in a room full of people. Part of the trick with 360 video in a VR headset is that you are having a blast while 4 other people have no idea what you're seeing. Being in front of a TV to experience 360 video is a social experience, and something we see as critical to the success of immersive content. It brings the same content that can be viewed in VR to a much larger audience. My family is loving it over the holidays!

Just tried it out. There's some great content in the app! This works for me even better than a phone app.

Well done guys! Still going strong I see...
