We've all seen sitcoms, laughed with them and probably even sung along to their theme songs. We occasionally find their jingles running through our heads: "Here's the story of a lovely lady," click, "Just sit right back and you'll hear a tale," click, "Where everybody knows your name." Their catchphrases pepper our vernacular: "Yadda, yadda, yadda." And their characters' tastes even influence what we drink -- cosmopolitans anyone? Who wouldn't agree that the backbone of American television is the sitcom?

In 1979, the New Wave band the Buggles sang "Video Killed the Radio Star." To be really accurate, they should have sung "television co-opted the radio star and made her its own," but it probably wouldn't have been as catchy.

The term sitcom is even short for situational comedy and was first coined by Variety.

The first sitcom centered on the most unlikely of characters: the zaftig immigrant doting wife, mother of two and good neighbor to all -- Molly Goldberg. In this article, we'll learn about early sitcoms, unlock the sitcom format and look at the future of American television.
