Blondie is a radio situation comedy adapted from the long-running comic strip by Chic Young. It stars Arthur Lake as Dagwood Bumstead and Penny Singleton as Blondie Bumstead for the majority of its run. The show's premise revolves around the comical misadventures of the Bumstead family and their daily struggles with a demanding boss, nosy neighbors, bills, and the art of building the perfect sandwich. Its tone is light-hearted and humorous, with a touch of zaniness, as the characters often find themselves in chaotic situations.

The radio program was broadcast on several networks from 1939 to 1950, including CBS, NBC Blue, NBC, and ABC. In total, there were 548 episodes produced. The show was also adapted into a series of 28 low-budget films, with Penny Singleton and Arthur Lake reprising their roles. The films were successful and ran from 1938 to 1950. Over the years, Blondie had various notable advertisers and sponsors, including R.J. Reynolds' Camel cigarettes, Colgate-Palmolive's Super Suds, and others. After Penny Singleton left the radio series in 1949, she was replaced by Ann Rutherford, Alice White, and Patricia Van Cleve. Later in 1957, Arthur Lake would return to the role of Dagwood Bumstead in the television series Blondie, this time opposite Pamela Britton as Blondie.
