Michael Zwerling, who owns a liberal and a conservative talk station in the Monterey Bay area, will next month drop the liberal format on KOMY-AM (1340) because it isn’t selling ads or drawing any ratings, according to the Mercury News. Zwerling’s conservative station, KSCO-AM (1080), has a 2.1 share of the area’s 550,000 listeners over 12, for 14th place in the ratings. In San Francisco, Clear Channel’s two AM stations, conservative KNEW (910) and liberal KQKE (960), were almost tied in the ratings a few years ago. Now KNEW has a 1.2 share of 5.8 million listeners over 12, double KQKE’s 0.6, according to the Merc. As the PPC reported Sept. 27, KQKE has dropped the team of former SF mayor Willie Brown and comedian Will Durst, who had been doing the morning drive shift since January. Now, KQKE will have no local weekday hosts. Program director Bob Agnew says, “[R]esearch shows that people would rather hear the national shows, like Al Franken and Stephanie Miller.”
