Cumulus Media announces that its legendary Fresno radio station KMJ-AM/FM “Newstalk 580/105.9” has partnered with Valley PBS to produce a one-hour documentary telling the story of KMJ’s 100 years on air. The program, “KMJ: 100 Years in the Valley,” is hosted by John Broeske and details the impact the station and its personalities have had on Fresno and the greater Central Valley of California over the past century. It debuted last night (3/30). KMJ hit the airwaves with just 50 watts of power on March 23, 1922. Eventually, with the threat of World War II looming, the FCC allowed KMJ to boost its power to a whopping 50,000 watts. “KMJ: 100 Years in the Valley” was written and directed by Emmy Award-winning filmmaker Jeff Aiello. KMJ program director Blake Taylor served as a producer.
