I agree though, that live sports are mostly watched at bars by friends in my age range. I only have DirecTV because it's "free" (included in hoa fees), but I still almost never watch "live" tv. I just watch DVRed shows instead of on Hulu now. Sports, especially NFL, are still huge as I can see by my facebook feed during big games or the draft.
Heck, I didn't know what a touch down was a few years ago, but sports are so popular among mainstream (ie: non techies) I had to learn enough to pretend to be interested to fit in socially, and eventually I started actually enjoying watching and following the local teams. I suspect there may be a bit of an echo chamber in some communities that don't care about sports, but I'd wager the among the majority they are still very popular.
Among me and my friends, nobody likes rap music, ice hockey or nightclubs, doesn't those 3 things aren't incredibly popular among many people.
