Thinking about this thread, and also reading the BBC article made me think.
When I was young, particularly during the secondary school years, I was always glued to the telly , even watching it whilst doing my homework. Now I rarely watch it for the sake of, unless there is something I specifically want to see (and there ain't much of that around at the moment). My wife on the other hand was hardly allowed to watch any telly when she was younger only "nice" things like Blue Peter. Now she will watch any old shite that is on ("Come Dine With Me" FFS!).
I have absolutely no idea what conclusions I should draw from this regarding our daughters tv viewing habits.
