How the Telephone Talks (silent, ca. 1920s)

“How the Telephone Talks” is an early silent educational film that explains the workings of the telephone using both live-action and animated sequences. Produced by Bray Studios in the early 20th century, the film provides a straightforward, accessible overview of telephone technology as it existed in the 1920s. It details the components and operation of telephones, including interesting elements like the use of carbon granules in the transmission process. Notably, the film features the original closing logo and has been appreciated for its simple and clear explanation of the subject matter. While there is some discrepancy regarding its exact release date—some sources cite April 27, 1919, and others suggest 1924—the film remains a valuable historical resource, even being preserved in the Library of Congress.
