I remember when TV had 4 channels. Everyone had the same shows in common. You could talk to people, did you see such and such. Now we have zillions of streaming services. Who has the money to afford them all? Who has time to watch them all? A magazine can do an article about a show you can’t watch. If someone says they watched something you have to ask where they saw it, and you might not have that service.
I also remember being told that commercials were why we could get TV for free. Now we pay for TV and still get commercials.
