History of KCSB

KCSB-FM is a long-running, student and community run radio station based at the University of California, Santa Barbara. Its history reflects both the evolution of college radio and the political/cultural shifts of the 1960s onward.

Origins (1961–1964)

  • KCSB began in the 1961–62 school year as a carrier-current AM station (meaning it broadcast only within campus buildings). 

  • It was founded by student Bill Harrison, initially called “Navajo Radio” after its dorm location in Anacapa Hall. 

  • Early broadcasts were very limited. Just a few hours per day at low power for dorm listeners.

In 1964, it became the first University of California stations to receive an FCC license as a noncommercial educational FM station, marking its transition to a real public broadcaster.

Expansion and 1960s transformation

  • Through the mid to late 1960s, KCSB:

    • Increased its signal strength and reach across the Central Coast

    • Expanded programming beyond early conservative formats into free form music, news, sports, and public affairs.

  • The station moved locations several times before settling near Storke Tower, becoming a hub for student media and free speech on campus.

1970 shutdown during unrest

  • On April 18, 1970, during the Isla Vista unrest tied to Vietnam War protests, the Santa Barbara County Sheriff’s Office shut down KCSB.

  • Authorities feared the station could spread information that might intensify rioting.

  • This incident is notable as the only case of police shutting down a radio station in the U.S. 

Growth into a free-form college station (1970s–1980s)

  • KCSB continued to grow technically:

    • Power increases (notably in 1964 and 1983)

    • Frequency changes (1976)

  • It developed a reputation for free form, alternative programming, typical of influential college radio stations of the era.

1989 controversy

  • The station gained national attention when it dismissed student host Sean Hannity after a guest made anti-gay remarks on air. 

  • The ACLU defended his free speech rights; KCSB offered reinstatement, but Hannity declined.

Modern era (1990s–present)

  • KCSB began webcasting in the 1990s, expanding beyond terrestrial radio.

  • It remains:

    • Noncommercial and student-funded

    • Open to both students and community members as volunteer DJs

    • Known for eclectic, independent programming (music, news, and public affairs)
