Dora the Explorer premiered on Nickelodeon in 2000 as an interactive animated series where young viewers are asked to shout answers and help Dora choose the right path. The blue cursor became a familiar part of that format, moving on screen to point at, circle and select items while the characters waited for a response. Clips and sounds from the show later spread through YouTube edits, classroom videos and meme soundboards, where the short click survived on its own as a nostalgic cue for finding, choosing and confirming something for an audience.
