Cowell wants US 'X Factor' to beat 'Idol'

Simon Cowell wants the US 'X Factor' to be more successful 'American Idol'.

The music mogul – who quit as a judge on 'American Idol' to kick start the new version of the pop star search show – will "die trying" to be the most watched programme, and he is confident 'The X Factor' will become the best series of its kind.
