Yes - during the N9
News 24 flags era there were very short interstitial bumpers/blips between promos - which were small flag animations in the centre of a black frame. They pushed the automation system quite hard.
Which is odd considering that break bumpers have been used for decades before News 24 came along, and of course Channel 5 that started a few months earlier had one between every advert.
Or was it just a quirk of the automation system, which I suppose wasn't specifically for channel playout
