First : Fandom. BTVS was my introduction to fandom. Yes, I knew about Star Trek conventions and fanfic. But Buffy got me involved. Buffy started just before we moved to CA. My sister watched it and I talked about it with them. In CA, I found on line discussion boards. Quotes, meanings, predictions, and other people jumping up and down about things you were jumping up and down. And people that saw things I missed. So I paid more attention, and rewatched, and had more fun with TV than I knew was possible.
Second: TIVO. Easy time shifting. The ability to pause and have a discussion in the middle of a show. ( I took DH and I well over an hour to watch an episode of Battlestar)The ability to rewind and resee the OMGWTFBBQ moments. But mostly the joy of turning on the tv and having something on that I want to watch.
Third: Hulu, itunes, and all the otherways I can watch tv on my computer. Tivo cuts off a few minutes– go find the show on the computer. Or everyone is talking about a show I didn’t see — catch the first episode on the computer to see if I care . Away from my TIVO– grab a computer and catch up on my shows. I know a number of people that had to give up cable due to cost — it really isn’t that painful anymore. Sometimes you have to wait a day — and one show I watch show the episode on the computer 8 days after the first airing. For someone that has benn timeshifting, this makes almost no difference.
Looking forwad to more changes
