San Bernardino is part of the Los Angeles Nielsen area. As such, most its residents receive the same local television and radio stations as residents of Los Angeles. KVCR-DT, a PBS affiliate operated by the San Bernardino Community College District, is the only local San Bernardino television station. KPXN, the Los Angeles Ion Television network affiliate, is licensed to San Bernardino, but contains no local content. Most of the northern section of San Bernardino cannot receive over-the-air television broadcasts from Los Angeles because Mount Baldy, and other San Gabriel Mountain peaks, block transmissions from Mount Wilson. Since the 1960s, most North San Bernardino residents have required cable television to obtain television. Today, the city has one main cable franchise: the city has Charter Communications. Mountain Shadow Cable is a small local company that provides services to the eponymous mobile home park. DBS satellite also has a presence. Local programming is handled by the city's Public, educational, and government access (PEG) cable TV channel KCSB-TV.
