What is the most famous circus in the world?

The most famous circus, nicknamed “The Greatest Show On Earth”, was the Ringling Bros. and Barnum & Bailey Circus, which had been founded in 1919 by an amalgamation of the Ringling Bros. Circus and Barnum and Bailey’s Greatest Show on Earth. The circus ceased operations in 2017. Since then, Cirque du Soleil has been considered the biggest circus show, and perhaps the most famous (who doesn’t know the name?).
