Another TV-free household here.
I had some of my daughter's friends over for a sleep over last year (ugh) and we had a 15-year old 26" Sony Trinitron CRT which I was ridiculed for by them as they all have massive plasma/LCD and 3D units.
For some strange reason I felt slightly guilty about this but after a discussion with the other half, we decided that this was the symptom of a problem with society rather than a problem with us and that it needed fixing.
Couple of days later, it went on the street with a sign taped on "Free TV". Within 10 minutes someone had taken it.
A year later, we all sleep better, we all communicate better and we are all a lot closer and we're also £150 a year better off (we have to pay TV license in the UK).
All it does is consume time and divide people.
