The only time I miss it is when I miss some huge event (earthquakes, shootings) and my friends look at me funny when they realise I haven't heard after 3 days.
On that note; I really want a twitter account that tweets these and a Facebook feed like algorithm that condenses my missed tweets for me so I can just see the major ones.
I only watch TV at the gym and when I visit relatives. If I watch video on my computer it is usually something I downloaded since Youtube is just barely "interactive" on the slow DSL connection which is all the phone company wants to sell me.
Right now the cable and satellite companies have a good business model that is still making money. The fact that so much Hollywood content is locked up with exclusive licensing deals means that this money train will keep them going for another decade.
Although the industry will do anything to keep the bundling model, they're very aware of the problems they're facing and they will make serious efforts to move towards a video-on-demand model.
Now, as for the very young, it seems that kids today don't have the attention span to watch whole television episodes. Friends come over to visit my ten year old son and it's often hard to get them to watch something like "Teen Titans" or "Card Captor Sakura" which they can watch Annoying Orange or Dovetastic Microwave Theatre or something else on Youtube.
I've also seen that today's kids just aren't used to sitting through several minutes of ads. It's enough to drive them to go outside and play.
I think cable is where the music industry was in the 1980's. They already were losing their audience, but the extra revenue they got as people replaced their record collections with CDs hid the fact that people didn't care about new music anymore.
