When did the Campbell Soup Company adopt the motto "Mmmmm mmmmm good"?

In 1929 the company opened a second major facility in Chicago. In the early 1930s Campbell opened Campbell Soup Company Ltd., in Canada, as well as Campbell's Soups Ltd., in Great Britain. In 1936 Campbell began making its own cans and in 1939 its agricultural research department was formed. On the product front, both Cream of Mushroom and Chicken Noodle soups were introduced in 1934, Campbell's Tomato Juice debuted in 1938, and Cream of Chicken hit store shelves in 1947. Campbell began backing these introductions with radio advertising in 1931, using the famous "M'm! M'm! Good!" slogan.
