Oh, the big media corporations would love to get back to commercials, commercials, commercials since that's the closest to what they know now.
The only problem is, that's not probably still not enough to replace all the revenue lost from cable, as the salad days of everyone paying for channels they never watched aren't going to come back. Of course, that makes the channels they rushed to add to cable systems redundant, as we saw with the ones dropped by Charter and soon every other cable system come negotiation time will do the same.
They're going to avoid it as long as possible, because it's very unlikely they'll be able to make as much money going DTC.
That point is very, very close though.
IMO, the closest thing to what we have now would be the former cable companies that became your internet providers start making deals to have their customers get the streaming services included in their internet subscription, i.e.:
CableCom Internet ACCESS Customers can pick from among X amount of streaming services and get one included. CableCom Internet MAX Customers get three, CableCom Internet EXTREME get all of 'em! (The ad-supported versions, naturally)
Internet providers send a little per customer fee over to the companies like they used to per subscriber, more eyeballs for targeted ads (that'll just ignore them while looking at their phones waiting for their content to start but don't tell marketers that!)
It won't be the same amount of money, but it'll be something. And those poor CEOs will have to make do with only one mansion in the hills instead of two, so sad.
Maybe that's the future, maybe not. Maybe everything goes the FAST-based route and it's all lean-back background noise while playing games on our device of choice.
