Maxwell House 1970s 

Maxwell House Coffee Commercial 1974.
Maxwell House was the long-time sponsor of the early television series, Mama (TV series), based on the play and film I Remember Mama. It starred Peggy Wood as the matriarch of a Norwegian-American family. It ran on the CBS network from 1949 to 1957 and was perhaps the first example of product placement on a TV show, as the family frequently gathered around the kitchen table for a cup of Maxwell House coffee. Early television programs were frequently packaged by the advertising agencies of individual sponsors. As this practice became less common in the late 1950s, Maxwell House, like most national brands, turned to "spot" advertising, with the agencies creating sometimes long-running campaigns in support of their products. One such 1970s campaign for Maxwell House featured the actress Margaret Hamilton, the former wicked witch in The Wizard of Oz, as Cora, the general store owner who proudly announced that Maxwell House was the only brand she sold.
