Файл:David Sarnoff with RCA videotape machine 1954.jpg

• The photo is similar to File:Sarnoff RCA videotape recorder 1954.jpg but this version includes a better look at the videotape machine in the event someone needs a photo of it.

• Though I see no information about copyright in this RCA magazine, a copyright renewal search was done at copyright.gov for the title Radio Age. There were no listings. There is no evidence of copyright being claimed on this material.
