TV news is such a joke, in 20 minutes you get to see 1 important topic of the day and a couple random things you don't even want to know about in a hope that they will tell you something interesting which will not be the case.

Using the web you can narrow that down to 5 minutes without occupying your mind memory too much to something uninteresting which I think is important to keep some room to fill in or use for your creativity.

Also for other reasons that TVs are not productive, I ditched that thing 10 years ago after getting out of college. Never missed it.
