Triumph of the Disc

Edison and phonographDisc records proved so popular that Columbia dropped them in 1909. By 1912, even Edison began offering disc-type phonographs and records for sale, although he continued to use his “hill and dale” type groove rather than the more popular “side-to-side” groove. Cylinder machines and records, however, were still produced until the demise of Edison’s Entertainment Phonograph division in 1929.
