humm.... theory.
when they bought rw, did it have a performance related get-out?

Ive seen these in contracts before (Ive had one!) and they are a way of not honouring the commitments you make.

here is a little story, maybe its true?

Five buy rw with a guaranteed audience of xxxx
if these figure are less than... say... 50% of that guarantee, there are contractual implications that benefit five in the event of a show bomb.

seeing the show was not as popular, or WANTING to break the contract for some reason, the confusion generated by changing the time would help lower the viewing figures.

just trying to make sense of it all with an even more stupid conspiricy theory.
