Cookie Monster Through the Years

The Evolution of Cookie Monster (1966-present)

As seen in	Year	Notes
unaired Wheels, Crowns and Flutes commercial	1966	Cookie Monster, first known as the Wheel-Stealer in an unaired commercial for General Foods' Wheels, Crowns and Flutes snacks.
IBM training film "Coffee Break Machine" and The Ed Sullivan Show	1967	The monster retains his teeth and his fur is dark green with a few brown-black patches.
Munchos commercials	early 1969	Arnold, a smaller, younger-looking version of the Wheel Stealer puppet, is created for commercials for Munchos. The puppet has lost its teeth and has light purple fur, appearing closer to the Cookie Monster that will debut on Sesame Street.
Sesame Street Season 1 - early Season 2	late 1969 - 1971	Back to his normal size and gaining his trademark blue fur, the monster puppet becomes Cookie Monster during the first season of Sesame Street. This puppet is scruffy and floppy as it is extremely loose and expressive.
Sesame Street late Season 2	1971 - 1982	Late in the second season, a more refined Cookie puppet is built with a squarer jaw. His eyes are moved higher on his head; further away from his mouth. For a few seasons, Cookie’s googly pupils are placed slightly lower, occasionally giving the impression that he’s looking downward.
Sesame Street	1982-present	Since around the mid-80s, two design variants for Cookie Monster have been used interchangeably: One follows the previous puppet design with a wide mouth and shorter shag fur; the other has a smaller, more curved mouth. Overall, Cookie's fur is now fluffier and lighter in color, and the size of his googly pupils has been adjusted.
