One of the San Francisco Bay Area’s numerous pubTV stations has dropped PBS membership in hopes of averting its sale. Hit by budget cuts like everything else in California’s public sector, San Mateo County Community College District gave KCSM-TV/FM a chance to cut costs, the San Mateo County Times reported yesterday. It is cutting six positions, five in TV and one in radio. Dropping PBS will save $400,000 a year, almost half of the $825,000 reduction planned. KCSM also plans to lease some spectrum to make money.
