As someone with a TV background, I feel a certain duty to defend it. There's some excellent factual TV, that is educational, informative, and aspires to make the world a more positive place, and really help people. Unfortunately, this is not always the television that people choose to watch! To be honest, I also watch some "rubbish" TV and enjoy it. But it's not true that it's all rubbish!
I'll be interested to see other people's answers.
