🕑 Added 2020-05-20 17:35:33 +0000 UTCmore at http://quickfound.net/
Theater promotion for the Western Electric sound-on-film recording system-- but silent.
Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

...The primary steps in the commercialization of sound cinema were taken in the mid- to late 1920s. At first, the sound films which included synchronized dialogue, known as "talking pictures", or "talkies", were exclusively shorts. The earliest feature-length movies with recorded sound included only music and effects. The first feature film originally presented as a talkie was The Jazz Singer, released in October 1927. A major hit, it was made with Vitaphone, which was at the time the leading brand of sound-on-disc technology. Sound-on-film, however, would soon become the standard for talking pictures.
By the early 1930s, the talkies were a global phenomenon...
In 1913, Western Electric, the manufacturing division of AT&T, acquired the rights to the de Forest audion, the forerunner of the triode vacuum tube... Beginning in 1922, the research branch of Western Electric began working intensively on recording technology for both sound-on-disc and sound-on film synchronised sound systems for motion-pictures.
The engineers working on the sound-on-disc system were able to draw on expertise that Western Electric already had in electrical disc recording and were thus able to make faster initial progress. The main change required was to increase the playing time of the disc so that it could match that of a standard 1,000 ft (300 m) reel of 35 mm film. The chosen design used a disc nearly 16 inches (about 40 cm) in diameter rotating at 33 1/3 rpm. This could play for 11 minutes, the running time of 1000 ft of film at 90 ft/min (24 frames/s).[ Because of the larger diameter the minimum groove velocity of 70 ft/min (14 inches or 356 mm/s) was only slightly less than that of a standard 10-inch 78 rpm commercial disc. In 1925, the company publicly introduced a greatly improved system of electronic audio, including sensitive condenser microphones and rubber-line recorders (named after the use of a rubber damping band for recording with better frequency response onto a wax master disc). That May, the company licensed entrepreneur Walter J. Rich to exploit the system for commercial motion pictures; he founded Vitagraph, in which Warner Bros. acquired a half interest, just one month later. In April 1926, Warners signed a contract with AT&T for exclusive use of its film sound technology for the redubbed Vitaphone operation, leading to the production of Don Juan and its accompanying shorts over the following months. During the period when Vitaphone had exclusive access to the patents, the fidelity of recordings made for Warners films was markedly superior to those made for the company's sound-on-film competitors. Meanwhile, Bell Labs—the new name for the AT&T research operation—was working at a furious pace on sophisticated sound amplification technology that would allow recordings to be played back over loudspeakers at theater-filling volume. The new moving-coil speaker system was installed in New York's Warners Theatre at the end of July and its patent submission, for what Western Electric called the No. 555 Receiver, was filed on August 4, just two days before the premiere of Don Juan.
Late in the year, AT&T/Western Electric created a licensing division, Electrical Research Products Inc. (ERPI), to handle rights to the company's film-related audio technology. Vitaphone still had legal exclusivity, but having lapsed in its royalty payments, effective control of the rights was in ERPI's hands...
Triumph of the "talkies"
In February 1927, an agreement was signed by five leading Hollywood movie companies: Famous Players-Lasky (soon to be part of Paramount), Metro-Goldwyn-Mayer, Universal, First National, and Cecil B. DeMille's small but prestigious Producers Distributing Corporation (PDC)...
