Who made the moonwalk popular?
MICHAEL JACKSON !
Michael Jackson made the moonwalk popular in the 1980's.
EDIT: Michael Jackson made the moonwalk popular, but the moonwalk was founded before he started it. The credit of inventing the moonwalk should go to the kids in a school in Kolkata who were reported too be the first ones to do the moonwalk. This is where Michael Jackson got the inspiration to do the moonwalk.
The Moonwalk was created by dancer Cab Calloway in 1932 and later perfected by tap dancer Bill Bailey in 1955. Break dancers used the Moonwalk in many of their dance styles and it later became a popular phenomenon when Michael Jackson used it at Motown 25. Since then, Michael Jackson has been known to be the best at performing this popular move.
