The station also has a public radio sister station, KRCB-FM. Much of the regular programming comes from PBS, American Public Television, and independent producers. Overnight programming is shared with the national satellite station Link TV and includes shows such as Mosaic: World News from the Middle East, while Create is simulcasted on DT2. The station receives annual about $500,000 from PBS.
KRCB first went on the air in 1984 by KRCB North Bay Public Media. KRCB North Bay Public Media was founded by Nancy Dobbs, president and CEO of KRCB North Bay Public Media.
KRCB shut down its analog signal, over UHF channel 22, on June 12, 2009, as part of the federally mandated transition from analog to digital television. The station's digital signal relocated from its pre-transition UHF channel 23 to channel 22.
KRCB agreed to move frequencies, while retaining its display channel number, in the FCC auction for $72 million on February 10, 2017. Proceeds will be used to start an endowment. On September 7, 2017, KRCB announced that it would acquire KCSM-TV in San Mateo from the San Mateo County Community College District for $12 million, using some of the money earned in the auction; the acquisition allows KRCB to expand its reach into the Bay Area, as KCSM-TV's transmitter is located at the Sutro Tower in San Francisco.
In one of the most crowded areas in the U.S. for PBS and public broadcasting, KRCB is notable for its coverage of local news and politics, and for the Emmy and Telly Award-winning, nationally distributed environmental series, Natural Heroes. KRCB also engages the community through local initiatives like North Bay Bountiful, a series of TV, Radio and digital stories that explore agriculture, food systems and environmentalism.
