Yep, that’s Betty manning the mic.
In 1924, just three years after General Mills created the composite Betty identity, it debuted “The Betty Crocker Cooking School of the Air” on Minneapolis radio station WCCO. Home cooks everywhere tuned in to listen to their trusted kitchen confidante—at the time, voiced by Marjorie Child Husted, who was also the first host and writer of the show. Betty’s advice became so popular that NBC picked up the program and aired it nationwide. It went on to become one of the longest running radio shows in U.S. History.
