When exactly did CBS and NBC cut from regular programming to cover this?
CBS had 8pm Elementary rerun, 9pm 48 Hours, 10pm 48 Hours.
NBC had 8pm NBC Movie, 10pm Get Out Alive pilot rerun...
Global had a movie and opted not to simsub the Get Out Alive rerun.
Fox had MLB special, with local news at 10pm.
ABC had 8pm ALL-NEW episode of Zero Hour, 9pm ALL NEW series finale of 666 Park Avenue that will NEVER EVER AIR AGAIN, and 10pm 20/20.
ABC was the only one with first-run burn-off episodes that night. CBS can easily rerun the 48 Hours episode, and NBC can easily air the movie again and air the Get Out Alive pilot again. Not the case for ABC unless the whole episode was pre-empted. They could have waited 15 or 30 seconds until the fade out to the executive producer's name. Anyways, on my VCR recording, there was a 5-sec countdown following the cut, and an introduction from a national ABC News anchor. It's not like they'd lose something big, like the suspect would run away, within those missing 15-30 seconds ! They cut away too early for no reason. Nothing was urgent.
