One of the things that really sets BBC and ITV daytime apart is live programming. Barring Jeremy Kyle, ITV has lots of live programming right up until the afternoon: Good Morning Britain, Lorraine, This Morning, Loose Women, and of course the ITV Lunchtime News. This Morning in particular I feel is still a real asset to the ITV daytime schedule being able to react well to the latest news topics as well as regular features, although I think it still misses Richard and Judy really (or at least, Philip and Fern).
That's not to say that the BBC daytime mainstays are any less popular for being pre-recorded content of course. As Brekkie says though, there does seem to be a lot of repetition within certain genres, as mentioned there are the antique shows, but also property shows and the consumer affairs programmes that keep Dominic Littlewood in work.
ITV don't have much to compete against the BBC in regards to daytime - it's a vastly superior schedule to that of BBC One and Two.
Agree - hate how it's crept into the weekend schedules and Bank Holidays too, which nowadays are generally just the standard daytime schedule offset by 15-30 minutes due to shorter news bulletins. The worst thing though (but not quite as bad as it was a few years back) is how many shows, antique shows especially, are basically the same show under a different title with minimal point of difference.
The BBC schedule is also very repeat heavy - credit where it's due but ITV is pretty much new content throughout the year, and if repeats are in the schedule it's an hour or two for a few weeks at most. It took ITV a long time really to fill the gap that axing CITV left, and it's arguably been the same for the BBC since dropping CBBC.
Even worse, the repetitive programming has festered onto BBC Two. Repeats on daytime have bordered up on BBC Two far more with the DQF cuts proposing that BBC One be the only channel to get new daytime content - with much of it being a tedious affair.
The BBC daytime schedule has become far too monotonous ever since CBBC and CBeebies strands were scrapped, by virtue of the fact that both channels would receive universal coverage on Freeview. There is only so much you can take of bloody antique and property shows as they feel like utter strenuous assault. The only show I find worth watching on BBC One daytime is Fake Britain to be fair.
