Bonjour,
The first musicals could be seen from the end of the 19th century in theaters. In New York, the famous theatre district hosting 41 theaters is called Broadway. This theatre district is still very popular today. The golden age of Broadway musicals lasted from the 1940s to 1860s.This period corresponds with the advent of musical films. In the 1980s and 1990s, the most famous musicals were action animated films. Live Disney musical films became successful again at the beginning of the 21st century.
