The very first hit factory was T.B. Harms, a Tin Pan Alley publishing company overseen by Max Dreyfus. With staff writers like Jerome Kern, George and Ira Gershwin, Cole Porter, and Richard Rodgers, T.B. Harms was the dominant publisher of popular music in the early twentieth century. Dreyfus called his writers the boys and installed pianos for them to compose on around the office on West Twenty-Eighth, the street that gave Tin Pan Alley its name, allegedly for the tinny-sounding pianos passersby heard from the upper-story windows of the row houses. The sheet-music sellers also employed piano players in their street-level stores, who would perform the Top 40 of the 1920s for browsing customers.
