Why it seems impossible? If you're a fan of a show that starts at 7:00 every day but you don't care about other shows before that, you'd end up in that pattern.

Even without watching scheduled TV, if you have a normal day things usually follow the same pattern. Finish work at 17:00, arrive home at 17:30 and all chores done by 19:00, time to watch TV!

Doesn't seem too impossible.

It's called a routine, it's not really unheard of...

I have a television that's about 20 years old with a built in timer to turn it on. I used it as an alarm clock back in school because I wanted to watch the news every morning anyway and it was much harder to "snooze" than a normal alarm clock.

Older generations that use TV magazines to plan their schedule.

This old TV doesn't have chromecast or netflix built in for on demand streaming

Little old ladies.
