TV was passive. You just sat there and watched what was broadcast after you selected a channel to watch.

The internet is interactive. This easily allows the internet to become a much larger part of someone's life than TV could.

This is a big enough difference between TV and internet that I don't think you can really use TV as a refutation of his argument about internet.

We are more unhappy when we compare yourself to people we see as being close to us. Most people wouldn't be jealous that brad pitt is living the dream but they would be very jealous if billy or jenna from down the street is always partying and living the good life.
