TV shows that moved channel?

With the recent announcement that Eggheads is going to be moving to Channel 5 after 18 years on the BBC, I'm wondering what other popular shows moved channels? I know Mastermind moved to Discovery and flopped at the turn of the century, and then obviously more recently, you have your Bake Offs, your Voices, and your Big Brothers- anyone have anything else?

I hope Eggheads gets better treatment than a previous BBC Two move to Channel 5, that being Robot Wars back in 2003.

After being given a fairly well advertised move to 8pm on Sundays it was moved to Saturday evening after a few weeks.

Suddenly, after a couple more weeks it was moved again, this time to ever changing mid afternoon times on Sundays.

Although some past familiar robots were missing and producer interference was rife, a lack of viewing figures were cited as the main reason for it's cancellation. No wonder given the way Channel 5 treated it.

Thankfully when it was rebooted in 2016 it was back on BBC Two, sadly it was just getting good again when it was axed after three series.

This happens a lot.

This is Your life was BBC for a few years, then ITV (Thames), and then back to the BBC.

It was also on BBC 2 with Michael Aspel and Challenge with Simon Mayo.

It was (and maybe still is) more recently part of “The Westminster Hour” on Radio 4, still credited to ITV.

Graham Norton's chat show. Arguably started on C5 when he stood in for Jack Docherty, then C4, BBC 2, BBC 1?

The BBC lost quite a few shows in 2015/16. Bake Off, The Voice, Family Guy, American Dad, F1 coverage as well, all went to different channels.
