Plot

This short was made for the express purpose of noting the 20th Anniversary of Warners' Vitaphone sound-on-film process and also was made to be released concurrently, and shown on the same bill, with Warners' Night and Day (1946). And that is what happened. If a theatre-goer saw "Night and Day" on first-run in any theatre, they also saw "Okay for Sound". Unless they arrived late, and then didn't stay for the "Extra Added Attractions".—Les Adams <longhorn1939@suddenlink.net>

This short was released in connection with the 20th anniversary of Warner Brothers' first exhibition of the Vitaphone sound-on-film process on 6 August 1926. The film highlights Thomas A. Edison and Alexander Graham Bell's efforts that contributed to sound movies and acknowledges the work of Lee De Forest. Brief excerpts from the August 1926 exhibition follow. Clips are then shown from a number of Warner Brothers features from the 1910s through 1947.—David Glagovsky <dglagovsky@prodigy.net>
