Interesting question. Hadn't really thought about it, but I'd say it has changed some. What I watch hasn't changed much. Always have enjoyed horror movies, sci fi, and comedy. But what has changed is my ability to have a computer in my lap while I watch. When I was kid I might play with something while I watched tv or sort baseball cards or whatever. Never just watching TV.
My kids will sit and watch youtube clips and stuff on their tablets, but I never see them. We don't allow snapchat or instagram yet for either of them and I hate both of them...total time suck with absolutely nothing of value on them. I'm going to have to start using instagram more for my business as people like it, but I see no real purpose to it other then using it as a marketing tool. I will never be a consumer of content there.
