I always assumed that Vaudeville was a mixture of off-the-cuff sketch comedy and pretentious Soap Opera.
And then I am reminded of Abbott and Costello’s infamous skit: Who’s On First.
Along with Charlie Chaplin, The Marx Brothers, The Three Stooges, Fred Astaire, and Judy Garland, Abbot and Costello were among the few acts that made a successful transition from Vaudeville to radio and television.
Because these disruptive technologies forced enterprises to change business models in order to survive, I wonder if there were many lawsuits from organizations similar to the RIAA and MPAA during that time.
