When the 1959 film Gidget became a hit, a local San Francisco television station held a beauty and talent contest to crown a teenage girl as "Miss Gidget" on the "Dick Stewart Television Show." Barbara won and was also offered the chance to be one of the regular dancers on the rock 'n' roll show "The KPIX Dance Party." She was on the show from 1959 until 1962.
