During the Edison era of the early 1900s, many Jewish immigrants had found jobs in the U.S. film industry. Under the Edison Trust, they were able to make their mark in a brand-new business: the exhibition of films in storefront theaters called nickelodeons. Within a few years, ambitious men like Samuel Goldwyn, Carl Laemmle, Adolph Zukor, Louis B. Mayer, and the Warner Brothers (Harry, Albert, Samuel, and Jack) had switched to the production side of the business. After hearing about Biograph's success in Hollywood, in 1913 many such would-be movie-makers headed west to avoid the fees imposed by Edison. Soon they were the heads of a new kind of enterprise: the movie studio.
