Ten years ago, the BBC launched BBC4 with the slogan "Everyone Needs a Place to Think". I wrote to them saying I already have one, thanks very much, and it's called BBC2 (they didn't reply).
Since then, I've gone digital and become a huge BBC4 fan. As for BBC2, it's obviously not a place to think any more.
I was looking forward to the new BBC2 series The 70s. I should have known better.
