The February 17 1949 edition of the Toronto Daily Star contained this ad:
Kate Aitken (1891-1971) was a broadcaster and cooking expert who started her radio show on CFRB in 1934. By 1950, she was so popular that an estimated 32% of Canadians listening to the radio were listening to her show. She received 260,000 letters a year, which required 22 secretaries to handle. She wrote or contributed to more than 50 cookbooks.
