History timeline

Tin Pan Alley publisher 
"Tin Pan Alley" was a specific area in New York City on 28th Street, between Broadway and 6th Avenue that, at the turn of the 20th century, was the center of the popular music publishing industry.  Many publishing firms were not actually located on that particular block, but, "Tin Pan Alley" was also as much a reference to a music industry district as it was to a music genre (popular music, ragtime – the precursor to what became jazz).  T. B. Harms & Francis, Day, & Hunter, Inc. was a Tin Pan Alley firm.

Sale to Warner Bros. 
As silent pictures evolved to talkies, Warner Bros. had aimed to build its inventory of published music.  Before the Wall Street Crash of 1929, Warner Bros. acquired Harms, Inc., using 140,364 shares of its own stock, then valued at $8,421,840.  Warner then reincorporated its acquisition under the laws of Delaware and named it Music Publishers Holding Company, Inc.  Also in 1929, Warner Bros. acquired the music publishing company of M. Witmark & Sons.
