Notes[]
The 1939 sign-on and sign-off are from September 21, 1939, when WFED, then CBS owned-and-operated station WJSV, famously collaborated with the National Archives to record their entire broadcast day. (The original recordings have since been added to the Library of Congress' National Recording Registry.)
