One of the signs that a programme isn't working is excessive tinkering with the peripheral parts of the format (in modern US television slang, this is known as "Jumping the Shark", the point were tinkering with a dying show actually kills it).

'ABC Club' starts life here on Saturday afternoon.  A week later, the programme has been moved to Sunday at 4.30, with a change in name to 'ABC TV Club'.  The programme has also moved up in its age range and now has Bill Allenby as a presenter.

A week later, and the programme is now called 'ABC TV Youth Club".  A week after that, it has gone, the slot now filled with a 15-minute sitcom and a puppet series, 'The Adventures of Noddy'.
