The Adventures of Rocky and Bullwinkle and Friends was an American television
cartoon series from the 1960s. Each half-hour cartoon episode included a short segment called "Peabody's Improbable History", with main characters
Mr. Peabody, a
genius,
polymath, and
bow tie-wearing
beagle, and Sherman, his adopted pet boy. The segment was conceived and created by
Ted Key. The machine was invented by Mr. Peabody as a birthday gift for Sherman. By enabling them to visit famous historical people or events, the Wayback provided educational adventures for Sherman. At the beginning of the cartoon segment, at the request of Mr. Peabody ("Sherman, set the Wayback machine to..."), Sherman would set the Wayback controls to a time and place of historical importance, and by walking through a door in the Wayback machine, they would be instantly transported there. Examples of people or historical situations visited are the
Marquess of Queensberry and the rules of
boxing, the imprisonment and memoirs of
Casanova,
Jim Bowie and the
Bowie knife, and the "
Charge of the Light Brigade". During such visits, the historical figures and situations encountered are always distorted in some crucial way. The main focus of Mr. Peabody and Sherman's adventures is thus the restoration of historical events to their proper course, albeit in a characteristically frivolous and anachronistic way. The machine apparently later returned Mr. Peabody and Sherman to the present, although the return trip was never shown. The segment traditionally ended with a bad pun. Either of the names Wayback or WABAC are in common usage, with the term "WAYBACK" explicitly indicated during the segment in which Mr. Peabody and Sherman visit the "Charge of the Light Brigade". The precise meaning of the
acronym WABAC is unknown. According to Gerard Baldwin, one of the show's directors, the name "WABAC" is a reference to the
UNIVAC I. Mid-century, large-sized computers often had names that ended in "AC" (generally for "Automatic/Analogue Computer" or similar), such as
ENIAC or
UNIVAC. The term "Wayback" suggests the idomatic expression "way back [in some former time]". == Adopted as an idiom by popular use ==
