Well I would expect he would be none too happy. In his day, the radio news was pretty much a headlines-only reading, and more emphasis on commentary and analysis. A stock phrase of the radio era was "See your newspaper for more details."A lot of stations were owned by newspapers, so it was self-serving as well.
Network TV news began as early as there were networks. But as far as being in any way in depth, forget it. There was only 15 minutes alloted nightly to the news, so it was still barely more than headlines, and an occasional photo. Separate single topic programmes like "The War As It Happens" were also offered. There were film presentations too, made by the newsreel companies, for instance The "Telenews" was produced by News of the Day, the MGM newsreel. But the film was of days-old events at best.
During Daly's career, technology advanced enough to have far fresher film, but the same quarter hour format was in place. (there wouldn't be a half-hour network news show until 1963).
In that short space of time, only the most important of the day's events got in. The stuff that's covered now, all the "health", "Life Style" and especially all the celebrity puff was never worthy of a dedicated newsman's coverage. Those things were reserved for other programmes, the chat and homemaking shows aimed at women earlier in the day. Now it's so saturated in with hard news, it's importance is now blurred as to bring it up to the level of what's actually useful to know, or perhaps, it's brought down the level of the hard news to it's level.
The old line newsmen/commentators are virtually extinct. News shows mainly feature a handsome younger fellow with an expensive head of perfectly styled fake hair, and a beautiful and equally vapid feminine counterpart co-hosting. They laugh and kid each other a lot. Daly and his breed were craggy, balding, average looking, and down to earth men that earned their fame and positions. Today's versions are closer to actors.
If female anchors are now in the majority, it's probably more on purpose than by chance. They're there to help make it more airy and pretty. Woman can do that. These female newsreaders ain't going to look like, or have the experience of the late Mary McGrory. With 24/7 news channels, to keep the audiences tuned in, they want to keep it as light as possible. I've been watching tv news for many decades, and I'll tell you- the changing way it's presented has definitely become less serious. It's a lot more technosavvy, and bigger, faster and flashier, but far more dumbed down. Would Daly be happy? Not likely.
