But presumably there's nothing technically stopping them from either binning GMB for the day or conversely, running it earlier and for longer? Would there need to be a cursory phone call to OFCOM or is it a case that ITV can basically run whatever they want? (I guess STV may have an opinion at the moment too)
Not wanting to take this too off topic but the breakfast license just seems odd. Apart from Thames/LWT I assume there was nothing written into the license that said a particular region couldn't be on air 24hrs if they wanted to? So did the IBA suddenly make up a breakfast license and all the other regions just went 'ok then'? Did none of them think they could sustain a breakfast show and so just rolled over at losing over 3hrs of potential airtime every day?
It seems odd in this day and age, but you're forgetting a very important part of this situation - the unions. They ruled ITV with a tighter grip than the IBA and would have been a key factor in any ITV company extending its transmission hours. Even if the network commissioned a centrally made programme, each region would have to run a fully staffed channel, including technicians to run the ads.
Would it have been worth all that negotiation, potential strikes, overtime pay for unsociable hours, just for three hours of television that at most would be watched by a couple of million? The ratings broken down between each region wouldn't be particularly attractive to advertisers.
I get the feeling that most of the network thought ITN would win and therefore they retained a vested interest without each having the huge overheads.
Of course, TV-am broke the unions so things have changed. Technology has advanced also, which makes breakfast television more affordable - and therefore if ITV just ran normal programming between 6 and 9:25, STV would have a huge case for claiming the slot for its own franchise. It is after all, paying a set fee per annum for ITV network programming.
