This logo is similar in resemblance to the longtime logo used by fellow PBS member station WGBH-TV in Boston. It also happens to have been designed by the same design agency, Chermayeff and Geismar. The "KPBS" text also looks similar to that of the 1971 PBS logo.
Following PBS, KPBS also got a new look, using the same font.
