This 1932 issue of Television News magazine would have the copyright renewed in 1960. Online page scans of the Catalog of Copyright Entries, published by the US Copyright Office can be found here. [1] Search of the Renewals for Periodicals for 1959, 1960, and 1961 show no renewal entries for Television News. Therefore the magazine's copyright was not renewed and it is in the public domain. |
