I'd miss TCM though.
Most of the classic films are on DVD or available streaming, from what I can tell.
I like some of the same channels your wife does, but I found they were getting so superficial, that I began searching out things I wanted to learn or do online. One site I found is called SmartFlix, where you can rent series of DIY tutorials. IIRC, you keep them as long as you need to. Not cheap, but it is a way to have intense How-To information right there to study and take notes from. I also found that a lot of the episodes on the DIY show are at You Tube.
Once upon a time, long ago, I was addicted to the women’s magazines. Then I noticed that they simply would recycle/rewrite the same or similar articles every few months or every season. Thinking back, I was attracted by the beautifully styled photos of whatever: a room. a dish, a cake, a garden. It was more of a fantasy experience than really doing something. It got boring and I became busier, so I stopped my subscriptions and now, I sort of smile when I see them at the checkout and they aren’t any different than they were 30 years ago, except the styles are modern. I think those how-to TV shows are similar.
Anyway, for now, everyone will do what makes them most comfortable. I didn’t pressure my husband nor did he pressure me. We just became aware how often we said “Seen it” or “There is nothing on”. At that point, we wondered why we were subscribing. The streaming option just means we have an alternative to the subscription.
