I think people are looking to much in to Daybreaks figures.
It was only ever going to get a slight rise from GMTV, on its first day. It was only ever going to get a few viewers that were interested in seeing the new show, a few BBC One breakfast viewers that wanted to sample it, the rest were going to be GMTV viewers.
I predict in the next couple of days the ratings will fall (i wouldnt be surprised for it to fall below 800,000 viewers in the next week or two), as the initial curiosity wares off, and some people will not like the new format (If it maintains its ratings then that is a sign that in the medium term it will grow quickly, however i think that is unlikely). The important figure is going to be in about 6 months times, when you will see if it can steadily increase its audience and challenge Breakfast over the next year or two.
As for BBW i actually think that is a good rating for an ITV drama. ITV drama just doesnt have a very good reputation at the moment, so they are going to find it hard to attract the big ratings. What they need to do is try and get back ITVs drama reputation, by doing a couple of drama a year that may not get above 4.5 million, but that get a name for being quality (not necessarily awards, but just seen as going back to the quality of ITVs previous dramas).
