KZNB

KZNB (1490 AM) is a radio station that broadcasts in a Regional Mexican format. Licensed to Petaluma, California, it serves the Santa Rosa area. The station is owned by California Broadcasting Corporation LLC.

The station's transmitter building and radio tower were featured in the film American Graffiti. The interior "DJ" scenes, featuring Wolfman Jack, were filmed at KRE in Berkeley, California.

On Tuesday, January 10, 1950 at 6 a.m., 1490 kHz commenced broadcasting as KAFP, which stood for 'Krowing Always For Petaluma,' associating the city with its poultry-processing status. Under the original ownership of Harold Sparks and Forrest Hughes, aka Petaluma Broadcasters, KAFP broadcast a hodgepodge of local and network/syndicated programs such as Sammy Kaye's music show, UP Radio News, a.o. For most of its life, 1490 signed off around midnight, though it was licensed to broadcast 24 hours daily.

KAFP, now owned by Lloyd Burlingham, became KTOB at 6:45 p.m. on January 10, 1961, eleven years after signing on. The format remained relatively the same, with a mix of news, talk, sports and music shows geared toward the Petaluma community.
