Wayback Machine (Peabody's Improbable History)

From Wikipedia, the free encyclopedia

Sherman and Mr. Peabody enter the Wayback machine ca. 1960 to witness another time and place in history.

The Wayback Machine or WABAC Machine is a fictional time machine from the segment "Peabody's Improbable History", a recurring feature of the 1960s cartoon series The Rocky and Bullwinkle Show.[1][2] The Wayback Machine is a plot device used to transport the characters Mr. Peabody and Sherman back in time to visit important events in human history.

The Rocky and Bullwinkle Show[edit]

The Wayback machine was a central element of the "Peabody's Improbable History" cartoon segment. The machine was invented by Mr. Peabody, a genius, polymath, and bow tie-wearing beagle, as a birthday gift for his adopted pet boy, Sherman. By allowing them to visit famous historical people or events, the Wayback provided educational adventures for Sherman.[3] 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 places or people visited are the Marquess of Queensberry[4] and the rules of boxing, the imprisonment and memoirs of Casanova,[5] and Jim Bowie and the Bowie knife.[6] 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 pun.[citation needed]

The Wayback has two main quirks. Firstly, it automatically translates all languages into English for their convenience. Secondly (and more critically), the historical figures and situations that they encounter are distorted in some crucial way. The main focus of the shorts is thus the restoration of historical events to their proper course, albeit in a characteristically frivolous and anachronistic way.

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".[7] 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.[8] 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 common expression "way back in [some former time]".[citation needed]

Mr. Peabody and Sherman film (2014)[edit]

The movie studio DreamWorks Animation announced in 2006[9] and again in 2012[10] that they were creating an animated movie entitled Mr. Peabody & Sherman, which was released March 7, 2014. The WABAC machine is a central element to the plot. In the movie, the acronym is revealed to be Wavelength Acceleration Bidirectional Asynchronous Controller (WABAC).

On another note, we got a nice letter from the last living director of the Rocky and Bullwinkle Show, Gerard Baldwin, because he read about the "fantastic project". Our Wayback Machine is a tribute to their more cleverly named "WABAC Machine" which in turn was a reference to the Univac. Sherman and Peabody live on.
