IAC is interesting to watch because of Ant and Dec but the simple fact that they don't mess with the shows ethos is also a factor. Viewers and voters get the feeling that IAC is run fairly and you very rarely hear of conspiracies and the like. BB has lost its shine because every year, the producers crap on the voters and viewers by changing things and running it their way. BB and CBB have lost the trust of their viewing public and IAC is still just IAC with funny trials and the same format.
