Maybe a different thought. I was introduced to a software capability that allows one to upload and manage TV channels not only to Roku but to Amazon Fire and Apple TV and soon to others . This could become the better comparable to what Microsoft is - software that sits behind the streaming juggernaut. And it includes all the tools to run ads on the standard 7 minute ad reel
