For the second time in three weeks, a newspaper has done a major story on KNBR 680, the all-sports station. On May 29, the Chronicle’s Tom FitzGerald looked at the station’s relationship with the Giants. Today (May 16), the SF Weekly’s Martin Kuz examines the station as it changes ownership. Kuz interviews Bruce Macgowan, John Shrader and Bob Agnew, all of whom used to work at the station. The story also hints at ratings problems for the station that is traditionally strong in the prized demographic of men ages 25 to 54. Kuz only touches upon perhaps the best known gaffe at KNBR in memory — the failure of the microphone of Giants announcer Dave Fleming when Barry Bonds hit his 715th home run to pass Babe Ruth. Kuz writes that “the early reign of [KNBR’s] new owners suggests a parent company struggling to adapt to big-market radio.”
