I sort of look at ABC in the 1970s the way I look at Fox today, but with ABC putting a lot more emphasis on news. Fox still doesn't have much if any impact on network news other than their Sunday morning talk show. ABC was trying to be CBS and NBC at least as far as influence and in size, but until Roone Arledge took over ABC Sports in the 1970s and then later ABC News in the 1980s, they were a distant third. Rooney Arledge with Monday Night Football and then Monday Night Baseball and ABC Sports college football, 20/20 World News Tonight, Nightline, This Week With David Brinkley, is responsible for making ABC the powerhouse it is today. With the ability to compete with CBS and NBC, when it comes to entertainment, news and sports. And have the affiliates to be able to do that. Whatever you think of this version of 20/20 and I'll get to that later, this was the start of ABC becoming a force in network news.
It's a damn good thing that Barbara Walters and Hugh Downs, became the anchors of 20/20. Even for 1978 the layout of this first show with two no-name anchors and one of them not even being an American and the other making his living as a writer and not a broadcast journalist and the cheesy music (even for 1978) and covering stories like how greyhounds are treated, just showed you that ABC News wasn't quite ready for prime-time. CBS's 60 Minutes even though they had already been around for ten years at this point, looked so much better and more professional. It looked like a network news magazine show. And not some weekend morning show that mixes in soft stories with a few real news stories and interviews, to make the show look serious. But they were trying and got much better again when Hugh Downs and Barbara Walters, took over the show in 1979-80. And were together for twenty years and made 20/20 the hit that it still is today.
