Does Dermott prefer X-Factor to Big Brother? (quote)
 

I just found this:

"It's the biggest show in the country. Unless you're Jonathan Ross or Ant and Dec... if you say you'd turn it down, you're full of s***" - Dermott Oleary, Heatworld interview about XFactor

I hope by that he means it's the biggest in terms of ratings or funding. Because if he used biggest to mean "best" then it's kind of insulting to BB lol.
