The Evolution of Oscar the Grouch (1969-present)

Image	As seen in	Year	Notes
	Sesame Street Season 1	1969	The original Oscar puppet is orange. This version, used in the early episodes of season 1, is built around a right-handed work glove, with no foam interior. At this time, the way the set is built forces performer Caroll Spinney to use his left hand, making this version of the puppet look awkward. This puppet's eyes can turn left to right.
	Sesame Street Season 1	1969	The second orange Oscar used in season 1 has a larger foam head. The set was changed to allow Spinney to work with his right hand.
	The Flip Wilson Show Episode #5	1970	Between the first and second seasons of Sesame Street, Oscar appeared on The Flip Wilson Show with a new design, including green fur and a blue eyebrow. His head had yet to take its final shape. Shortly after, in the second season premiere of Sesame Street (Episode 0131), an altered version of this puppet would be used as Granny Grouch.
	Sesame Street Season 2	1970-1984	For the second season of Sesame Street, Oscar's eyebrow has changed to brown, and his head has been remodeled into its final shape. Although the puppet has been rebuilt since the 70s, the design has stayed consistent. In The Wisdom of Big Bird, Spinney says that the current Oscar's eyebrow is still the same piece of fur used in the original orange Oscar puppet.
	Sesame Street Season 17	1985-Present	Oscar's fur is less messy than the 1970-1984 version. His eyes are also just a little farther apart.
