I've never really had the patience for TV, but whenever I'm staying at my boyfriend's brother's place we all end up watching a lot of Netflix together on our shared account. Like, seriously, a whole one or two hours a day. I also use Youtube for language practicing, which basically counts as TV in my mind!
I now understand that it's also a form of socializing, as you mentioned, but I know if I ever return to living alone tv shows/movies would be one of the first things to go!
Oh yeah, the internet can be a TV too, especially youtube!
How we manage our time in front of the screen would really be up to us.
