R&B and Soul

In 1958, KSAN switched to a full-time

music format, targeting black listeners in the Bay Area, the first station on the local dial to broadcast R&B around the clock. KSAN's transmitter was on top of the Merchandise Mart building on Market Street, where the studios were located. Until the 1950s, San Francisco radio stations devoted little time to "ethnic" programming of any kind, with the exception of KSAN and KWBR, which also broadcast programs intended for the Chinese, Italian, Portuguese, German and Japanese communities. On July 3, 1964, KSAN was sold to John F. (Les) Malloy and Delmor A. (Del) Courtney, two well-known San Francisco radio and television personalities. Malloy was for many years a star on local radio and had hosted a popular TV talk show on KGO-TV in the 1950s, while Courtney found fame as a bandleader and personality on

stations available on the FM dial by the 1970s, KSAN concentrated on other underserved communities in the Bay Area, including ethnic groups looking for radio programming in their language. The station became KEST. In 1974, KEST changed its format to a mix of old time radio dramas, comedy recordings known as "Freeway Funnies" and talk shows. The station was known as "KEST Theater Of The Air". In 1977, KEST dropped the old time radio dramas and talk shows and changed formats to religious programming but surprisingly kept the "Freeway Funnies" until 1980. In the early 1990s, KEST adopted a multilingual ethnic format and became part of Douglas Broadcasting.
