Google’s doodle looks a bit different: instead of the regular primary-colored G-O-O-G-L-E, Big Bird, the giant yellow bird character from the children’s television show Sesame Street, is featured front and center.

Why the switch? Sesame Street, brought to you by the Children’s Television Workshop, is celebrating its 40th anniversary!
