Charlie Chaplin During 1915, Chaplin became a cultural phenomenon. Shops were stocked with Chaplin merchandise, he was featured in cartoons and comic strips, and several songs were written about him.

When the Essanay contract ended in December 1915, Chaplin – fully aware of his popularity – requested a $150,000 signing bonus from his next studio. He received several offers, including Universal, Fox, and Vitagraph, the best of which came from the Mutual Film Corporation
