You probably missed Moving On, being go-getting types who don't lie on the sofa at 2.15 in the afternoon, eating Sugar Puffs and flicking desultorily between Classic Mastermind and Dickinson's Real Deal. What's more, you're probably not all that worried about having missed Moving On, daytime drama not exactly having a premium status. Moving On is slightly different though.

"This is a post-watershed programme and contains adult content and language," read an advisory note on the screener version of Way to Go, a new BBC3 comedy about euthanasia. Thoughtful of them to point that out, but I do wish there were times when that was a guarantee and not a warning. And I'm not thinking about Way to Go particularly (more on that later) but about The Genius of Invention, a new BBC2 series about British inventors.

Bob Servant apparently owes his existence to email scammers.

One day someone will take away BBC4 and there will fall across the land a mighty lamentation, even though relatively few people watch it now and we all pretty much take it for granted.

You can have 20 minutes of Ricky Gervais's time for about £25,000, but Michael Mansfield is going to cost you a bit more – up to £40,000, according to Funny Business, Richard Marson's intriguing series about the economics of the comedy boom.
