Several years ago I had read on a forum that the archive of former ITV franchise Television South (TVS) was missing. Then it was discovered that the company archive, which had eventually after many takeovers landed with Disney, was still in existence but important documentation surrounding the various materials had been destroyed. This meant even though tapes still existed, documents surrounding rights did not. If this is the case why are Disney, a multi-billion dollar company, unwilling to sort out the matter instead of burying their head in the sand as they are currently.
TVS were most famous for Art Attack, Catchphrase and Fraggle Rock, the latter two currently missing and unable to be released because of this conundrum.
Perhaps somebody could shed some light onto this legal mess.
An Art Attack TVS show (the one where Neil Buchanan made the Queen's face with £250k in £10 notes) was shown during the CITV Old Skool Weekend and I think it had a copyright year of 1992.
But anyway to cut a long story short, it continued after TVS lost its franchise because Neil Buchanan set up his own company, bought Art Attack from TVS, it continued to run on ITV until 2007 and the company was bought out, then later sold to Disney, who now own the format and resurrected Art Attack for Disney Junior.
As to why Disney show naff all interest in it, typically because they see it as worthless (due to lack of paperwork) and would spend more time sorting it out than what they would make back in it. So it languishes somewhere, unloved.
Clips of TVS Catchphrase were used (under fair use) on ITV's Saturday Night Gameshow documentary so the archive is definitely accessible to ITV. With regards to All Clued Up - Gordon Burns, host of Krypton Factor has stated before he gets sod all when Challenge repeats it so I dare say the same may apply to David Hamilton.
