Movie actors had to migrate to TV several times over the past 60 years ago, so its not a new deal.
In the last 10 years I have gone to maybe 5 movies at a theater, with more years between each time.
The cable channels started making their own in house programs quite a while ago. Most were not noteworthy for me. One of the first ones I remember was Showtimes Sherman Oaks, a comedy. Big digital companies like Amazon have recreated the Hollywood movie studio atmosphere. The productions range like the Hollywood studios did in their hey day, from A list, to B, C, D, And F, for time fillers, paying actors to practice acting.
I have Acorn and Amazon and an outdoor antenna. On Amazon I watch The Expanse and Bosch, that's it for their home grown continuing series, watch old stuff as I think of it. Have watched some of their shows that only were made for one season. For the antenna, the public broadcasting channels have new stuff, the bulk of the rest of the outdoor antenna is 10 years or older. Its hard for me to think of the small screen as small every time I see someone lugging a 5 foot tall TV out of Walmart. 2 feet tall is the biggest I got, 1 from a yard sale, the other, an old picture tube model.
Dvds, no Blu Rays.
I noticed that the same way book trilogies are marketed, Amazon has started running the first season free for some programs with multiple seasons, then you have to pay one way or another to see the rest of the seasons. I don't pay, I just find another one to watch for free.
I use a Roku box. I sold the Apple TV on eBay.
Digital entertainment is advancing on multiple fronts, but the next big thing, like maybe virtual reality home theater movies is still a ways off, so it seems like the only draw for now are the ever increasing screen sizes.
