I haven't had a TV for about 14 years. I lived without one for much of the 80s and early 90s when I was a daily newspaper journalist working shifts and never in in the evening, then I moved to New Zealand for several years through to the mid 90s and never bought a TV either. So I got used to it.
When I lived in New Zealand I used to go to a mate's house to watch Star Trek: TNG, and Star Trek (Voyager and DS9) was about the only thing I watched when I did have a TV through the late 90s and early 00s, which was mainly used to entertain the kids when they were small.
I see no need for a TV - I have a few web and magazine subscriptions, I read a lot of books, and my evenings are largely spent cooking, eating or listening to music.
Occasionally I join up one of the streaming services if there's something I want to binge-watch on the laptop. (Did that with Game of Thrones last year). In reality the only time I miss TV is on election night.
I don't go much to movies either - the only time I ever see them is on regular long haul flights to Asia. I had an ex who used to drag me to horror movies and 30 years later I still get sweaty palms going into cinemas (my body anticipating some gory shocker even if it's only Mission Impossible).
The down side is huge distraction if I'm anywhere there's a screen with something on, my attention gets sucked into it as it's an unusual thing for me, I'm also extremely intolerant to random/ambient crap music which I suspect people get de-sensitised to if they watch much TV.
EDIT bloody hell this is a thread resurrection and a half!
