ITV should now realise its overkill. They already shot themselves in the foot by starting at 7:30pm, when they have been familiar with the 8pm start-time for nearly all the live shows. I don't know why ITV would change this, even for a few quite rubbish Susan Boyle/Cheryl Cole shows.
They are too similar to X Factor, and that's why they're not going to be popular. Having a 12-13 million show is a good thing, but I don't think it should be leading in (or leading out) from a show which is essentially very similar.
ITV should be launching dramas. In America, the Superbowl was used for exciting new family dramas (The Wonder Years in 1988, for example). And that got mammoth figures. Why waste it on entertainment?
I think people like entertainment in smaller doses. The rule is excepted with X Factor and Britain's Got Talent because of their popularity, but generally, I don't think anyone's going to watch essentially the same show for 3 hours a night.
ITV have messed up with The X Factor. The 2 day spread worked up until around the last 6, when people got bored because of Jedward, and obviously now it shows. Noone wanted to tune into the Saturday show.
So, next year, ITV would be best, from the last 6, having the show on one day, either Saturday or Sunday, but probably Saturday, and making it far shorter:-
7pm-8:30pm X FACTOR FINAL
8:30-9:30pm FAMILY DRAMA
9:30-10pm X FACTOR FINAL RESULTS
10pm News at Ten
This year, that would've left the Royal Variety naturally on Sunday.
