Pre-KLCS Years, 1957-1973

In October 1957, the Los Angeles Unified School District began producing televised instructional programs to be viewed in school by its students. By the 1966-67 school year, it was producing over 700 TV programs per year for broadcast on various local stations in the Los Angeles area and leasing airtime to broadcast 40 hours of instructional programming Monday through Friday each week. Over the years the district earned the support of teachers and administrators who were impressed with the effectiveness of the programs on the learning experience in the classroom.

In 1963, the LAUSD began the application process to acquire a license from the Federal Communications Commission and launch its own TV station, with UHF channel 58 its designated location on the dial. The district also applied for in 1967 and later received state and federal grants to build and equip a broadcast facility for the new station. In the summer of that year, advocates for the LAUSD testified before the FCC on the benefits of an instructional TV station for students, staff and the local community. Five years later, on March 3, 1972, the FCC granted the district a license to broadcast on channel 58, and the new station began operations on November 5, 1973 as KLCS, the call letters an apparent acronym for Los Angeles City Schools.
