A lot of the success of Nightline was the fact that it was built around a single anchor, speaking to newsmakers. Once the show format changed, with multiple hosts, and feature reporting, it became more of what you see on the cable news channels and other places. To me, it really doesn't matter what time it's on, because if that's really what I want, it's available 24/7 someplace else.
Exactly. it's worth remembering the history of
Nightline. It started as a nightly report in 1978 or 79, anchored by Ted Koppel - about the Iran hostage crisis, after the fall of the Shah. In fact, I think the original title was
America Held Hostage...the
Nightline brand came later. At the time, it was a smart move by ABC, which really had nothing much going in late night. Their biggest hit had been Dick Cavett, who always trailed Carson in the ratings, and his show had ended a couple of years previous, in any case.
In my opinion, the show went to hell after Koppel left - perhaps not because he left, but because they decided to tinker with the format.
Besides, from what I gathered at the time the two shows switched time slots, it was because ABC felt Kimmel was at a disadvantage by starting a 25 minutes after
The Tonight Show and
Late Night. It's Kimmel's show that gets all the buzz, gets quoted, and portions streamed on the internet the next day - not
Nightline, which is more or less an anachronism in our 24/7 news world.
