Supernatural - 9 or 10 on ITV2, around 11 if it's on ITV1.
Numb3rs - ditto on ITV3, ditto on ITV1.
The Inside - late on ITV4, never on ITV1. (Admittedly it didn't really deserve any better.)
Friday Night Lights - 8pm on ITV4, never on ITV1.
Surface - early evenings on ITV2, Saturday afternoons on ITV1 (and terrestrial didn't even complete it).
Entourage - late on all its ITV channels.
And so on. And they got Law & Order: Trial By Jury (the only Law & Order series to be a flop). Way to go, ITV. Still, they have to come up trumps sometime.
