This "great new art" used by Paramount, Warner Brothers, Hal Roach, Columbia Pictures, Christie, Universal, United Artists, Harold Lloyd, Fox Movietone, and Metro Goldwyn Mayer, as pioneered by the world's leading makers of telephones, switchboards, cable, trans-Atlantic telephone equipment, telephoto machines, and public address systems?
Yes, it's "Sound Pictures" ("The Voice of Action") provided by Bell Telephone Laboratories and Western Electric. They were responsible for the Vitaphone and the Movietone, and they practically shove the reader into a cinema seat with their final paragraph.
The success of Sound Pictures is history now. Continuing progress is certain. Make sure of enjoying it. Go to the theatres showing these great producers' pictures with the sound equipment recognized as the world's standard.(The New Yorker, June 8, 1929...a particularly good issue, by the way).
