I worked at one particular station in the early 1990s where the board ops (remember them?) on the AM side, which was a news/talk ABC affiliate, had to record the ABC News satellite feed at I believe :55, then they had 1 minute to rewind and cue it up for playback at the TOH. Occasionally if they forgot, some board ops would re-run the previous hours' recorded news, while others would just air the TOH news direct from the satellite feed. Eventually they got in trouble from station management, as they explained they were contracted to carry the news programming that was fed at :55, but not the one of equal length that ran at TOH. From what I recall, the :55 and TOH news had different intros, with the one at :55 always starting with "Direct from ABC News...."
