Re: formats. Late 90s and early noughties new game show formats seemed to be cropping up weekly, but struggling to think of the last genuine new game show hit, especially in primetime. Most of ITV's efforts in the last decade have been celeb versions of their daytime shows and although the likes of Tipping Point, Tenable and over on the BBC Impossible have secured their place in the schedules unless I'm forgetting something obvious (and I probably am) the last game show on British TV which seemed to offer something new is possible The Chase, and that's a decade old now.
I preferred the internet when it had a sense of humour.
