The Follies were lavish reviews, something in between later Broadway shows and a more elaborate high class Vaudeville variety show. Many of the top entertainers of the era appeared in the shows. The Ziegfeld Follies were also famous for many beautiful chorus girls.
After Flo Ziegfeld's death, his widow authorized use of his name for Ziegfeld Follies of 1934 and 1936. The name was later used by other promoters with less connection to the original Follies.
There was also a 1946 feature motion picture entitled "Ziegfeld Follies", reprising a number of historic songs and acts from the Follies; see: Ziegfeld Follies (1946 movie).
