It became "8 out of 10 Cats Does Countdown" which is still going.
Its cheaper and easier to make a show where the contestants play simple word games and banter, than make a show with current affair questions and researchers. The comedians just turn up and do their stuff, wirhout any researchers or question writers needed. There are still comedy writers of course, as the show does have sketches and bits throughout.
But the games really pad out the show, although personally i find ir a bit tedious to watch. The countdown version runs for an hour while the original ran for 30 mins.
