Ted talks
I have an OTA (HD) DVR. I record the news 3 times a day so I can virtually always catch the latest - I don't watch it all (sports and politics annoy me), I don't even watch each episode I record.
I record a few informative shows, like Dr Oz. I only watch the ones with topics that interest me.
I record a handful of prime-time shows. I like APB the best, but I worked in IT and it's getting unbelievable...
I record all the late night talk/entertainment shows - again, I only watch what interests me and don't watch every episode. But in general, daytime TV annoys me.
I use titantv.com - it allows me to set what channels I get - and watch, It will filter for just movies (or sports or a bunch of stuff) and shows their synopsis and rating. There are LOTS of good, classic movies on the sub-channels (12.2, 18.3...).
I actively avoid watching 'live TV', because I can't skip the ads.
Occasionally I watch youtube - but it tends to be a time sink.
