Victrola. Originally, a phonograph from the Victor Talking Machine Company, Camden, NJ, but it eventually became more of a generic term for any brand of phonograph.
One of Victorâs key innovations was to get rid of the bulky sound horn, which customers found to be an intrusive presence in their homes. In 1906, the first Victrola was introduced. It basically took the playerâs sound horn and pointed it toward the floor so that is was hidden within the machineâs cabinet.
