To be honest, though, Coronation Street is scheduled pathetically. Wednesday's are a write off thanks to the football, but they should've at least looked at Tuesday's when thinking about the change. I agree, the show could probably do without another schedule change but as I said above, ITV need to thinking about the overall brand, not one show inparticular.
Monday: 8.30pm
Tuesday: 8pm (hour long)
Thursday: 8.30pm
Friday: 8.30pm
ITV become immediately more competitive on a Tuesday night with Coronation Street anchoring the 8pm hour. It's also spread more throughout the week rather than airing five episodes in three days. The silly divided episodes are dropped.
The only thing I'm not happy about with the above is Thursday's episode starting at 8.30pm; it really should start on the hour so it doesn't begin halfway through a BBC1 hour long but it'd be ridiculous to have a 60 minute gap between two Emmerdale's.
Monday and Friday's would be weakened, admittedly, but frankly Friday isn't a huge issue as most of the advertising audience is out then anyway (hence ITV's half-hearted efforts in the 9pm hour in recent times) and Monday seems to be ITV's day so will hold up better than any other night (and Coronation Street still leaRAB into the 9pm hour). Besides, I think the benefit to Tuesday would outweigh the minor damage to Monday and Friday.
I think a Coronation Street lead in would give ITV more confidence to try 'big' shows on a Tuesday night against what is usually weaker opposition. Understandably, they don't appear to have much confidence on the night at the moment.
Sorry this is longer than I thought it'd be and everyone'll probabaly disagree with it anyway.
