Was the BBC version an independent production or a BBC production?  It would be interesting to know how it ended up moving to ITV with the host on board too.    If it was an independent it's easy to see how they just moved for more money, but if it was a BBC production I'm guessing ITV or an independent company had to swoop in for the format rights (is Match Game in the US the original?)

Obviously were other shows in the 90s which switched from ITV to the BBC too, notably This is Your Life and Through the Keyhole.

The first BBC One revival was made by Fremantle UK IIRC it was taken over by Grundy in 1999 who continued to make it on ITV. Thames was responsible for the 2016 ITV revival and the current BBC revival. The original run was a BBC production as indies weren't around until the creation of Channel 4.
