Background: KPBS is a PBS affiliate located in San Diego, California. KPBS was founded in 1960 by San Diego State College (now San Diego State University), as a radio station that went under the name KEBS; in 1967 KEBS began broadcasting on television as an NET affiliate. In 1970, after NET folded into New York City/Newark station WNDT (now WNET), PBS absorbed NET's operations and KEBS changed its name to KPBS.
1st Logo (1977-1984)
