Top 40 News
I guess I was a weird kid, but unlike my friends, I stayed tuned into Top 40 stations when the news was on. As I remember it, Top 40 stations mostly ran short newscasts (2-4 minutes) on the hour and half hour from the 50s to mid 60s. I grew up in LA, and seem to recall that KFWB tried counterprogramming KRLA for awhile by running news just before the hour and half-hour. In 1965, Bill Drake programmed stations took over the radio dial, and mixed it up further with "20/20 News," which ran at:40. Their weekday anchors were either stentorian sounding and had deep voices (Marv Howard) or were downright pompous and theatrical, like Jaaaaaaaay Pauuuuuuul Huddleston. They were a lot of fun to listen to. 20/20 News had teletype sound effects and jingles for sports and weather. I recall that Drake was quoted as saying (paraphrasing), "If I have to run news by FCC rules, we will produce an excellent news broadcast." I recall that they paid extra money to run nation wide reports from UPI, and had a number of local field reporters in LA. By the late 60s, KHJ and other Top 40 stations made their newscasts longer (10-12 minutes), but only ran them 3 or 4 times a day outside of morning drive.
KHJ and most other Drake stations ran straight-forward news. I believe CKLW was the only Drake station into that blood-spattered, gory and sensationalism thing.
In the late 60s, KFWB became LA's first all news station, and KRLA tried being the hip counter-culture AM rock station, including a satirical left-leaning news program called "The Credibility Gap." One of the "news" people on that program was Harry Shearer, later of Saturday Night Live, various voices on The Simpsons, Le Show on NPR, and many many voice-overs. Two other actors on the show were David L. Lander and Michael McKean, later Lenny & Squiggy on Laverne & Shirley. McKean, probably now in his 60s, still gets a lot of work in films and TV.
The Gap staff eventually wore out their welcome with KRLA management, and the station reverted to a more KHJ style newscast with the likes of Paul Oscar Anderson, another in a long line of pompous Top 40 newscasters, and an expert in the "prenant pause...he signed off with; "This (3 to 5 second pause) is Pauuulll OSCAR Anderson."
In the Bay Area of the 70s and 80s, the only equivalent was a guy named Gil Haar who worked at a number of AM and FM rock stations, and signed off with ..."and that's the news, so now ya know." He retired about a decade ago.
Most of these anchors have disappered - an anachronism I guess. The only exception I've heard in the past few years is the semi-pompous Doug Limerick on ABC radio news, and I've heard he worked WABC during their Top 40 format in the 60s and 70s.
