There was a relatively short time when Central did local bulletins (albeit international, national news as well) through the night. Quite a few examples on YouTube. In the "More Central" branded era. But of course that is 25 years ago now I would say!
Sorry for the double-post, but I think the overnight bulletins in Central disappeared when ITN began providing overnight updates sometime in 1988. Central were one of the first regions to begin overnight or late night broadcasting, and it wasn’t until most regions had started their overnight service that the ITN Morning News and overnight bulletins began.
We’ve discussed before whether regions were allowed to record the news summaries and play them back, as not all regions followed a common overnight schedule. A YouTube clip shows a bulletin rewinding on air in one region (maybe Anglia). I wouldn’t have thought it was a big deal for regions to time shift these summaries but there is always the danger of out-of-date news, especially a developing story, or a region playing back the wrong summary - and this wouldn’t reflect well on ITN. Perhaps they read the bulletins live as often as required, even if they were only being part-networked?
