Below is another interesting clip from earlier in 1978 -- "ABC Evening News" before the launch of "World News Tonight," but after Roone Arledge had taken over ABC News. Barbara Matusow describes that transition period in her 1983 book The Evening Stars: The Making of the Network News Anchor:
"[Arledge's] most immediate problem was what to do the incompatible team of Barbara Walters and Harry Reasoner. Arledge's initial move was to buy time by making format changes designed to minimize their impact on the Evening News while he was working on a replacement formula. "Two-shots" were eliminated, meaning that Walters and Reasoner were not shown together on the screen, and something called a "whip-around" was introduced -- correspondents handing off their reports directly to each other instead of going back to the anchor for introductions. Subanchors began to appear: Frank Reynolds was featured prominently in Washington, as was Peter Jennings from various European capitals."
In other words, the final reincarnation of the "ABC Evening News" already looked a bit like "World News Tonight," which launched a few months later.
(As the following clip for two years earlier illustrates, "ABC Evening News" before Arledge was very different:
