The thing was it depended on who owned your local ITV area, for when WoF was broadcast in your area. During 2000 If you lived in Carlton or SMG areas you would get Wof every week day at 5.30 no questions asked. The other areas: Anglia, Border, Granada, Meridian, Tyne Tees, Ulster and Yorkshire aired the episodes at 2:40pm, and of course not during the summer. SMG liked to put out its local show in peak time around this era.. Again during 2001 except for Meridian, Yorkshire, Tyne Tees. The problem was Granada was getting its dirty hands on all of ITV and there wanted something else in that slot.
Let's be fair here ITV had half decent format filling up the time slots, during a period where its just lost Home and away and was still having trouble filling the 5pm arae. So what does it do bring in crossroads and not kept WoF to have a stable schdeul
Fun house was already axed in 1999 replaced with Twister which just never took off..
Though the 2001 era of WoF only lasted for a short run, that run was repeated sporadically on ITV1 up until 2004.
Note the interesting Jenny Powell gag at the start of the second game.
Of course at this point ITV was becoming more centralised and therefore whereas the previous John Leslie 'mega-run' of hundreds of episodes survived purely on particular regions thirst for the show, schedules became normalised nationally so this was no longer possible. Also, SMG was slimming down itself so its own network productions came to a halt - as it was the same time that production of Fun House stopped too.
The rise in big budget prime time gameshows was also booming by this point too, so it was overshadowing the lower budget gameshows and ITV commissioners appetite for them diminished, who they no longer saw much of a future in them (Supermarket Sweep and Bruce's Price is Right amongst others all ended production at a similar time). Catchphrase and Family Fortunes survived, but only after being turned into cheap daytime fodder and they didn't last that much longer either.
