In 1917, Sennett gave up the Keystone trademark and organized his own company, Mack Sennett Comedies Corporation.{{sfn|Sennett |1954|p=}} Sennett's bosses retained the Keystone trademark and produced a cheap series of comedy shorts that proved unsuccessful. Sennett went on to produce more ambitious comedy short films and a few feature-length films.{{sfn|Sennett|1954|p=}}

Many of Sennett's films of the early 1920s were inherited by [[Warner Bros.]]<ref name="Walker, Sep. 3"/> after Warner had merged with the original distributor, First National. Warner added music and commentary to several of these short subjects, and the new versions were released to theaters between 1939 and 1945. Many of Sennett's First National films physically deteriorated due to inadequate storage. Hence, many of Sennett's films from his most productive and creative period no longer exist.<ref name="Walker, Sep. 3"/>
