Original text : *The kinescope of the entire 30 minute broadcast has no copyright marks. Television was done live at this time and what survives of it was because a kinescope was taken of the broadcast. It was uncommon for television programs to have copyrights at the time; the only way to record the shows was via kinescope and the machines were common only in broadcasting--viewers had no way to record a motion picture-like copy of the television video and audio.
WNBT--the call letters of NBC's flagship New York television station at the time-it later became WNBC-TV. No information.
National Broadcasting Company--for the year 1977. This is when any copyright which may have been valid for this program would have needed to be renewed. No information for this particular television program was found.
Working on the premise that this program may have had a 1949 copyright, there is no evidence that it was renewed.
There is no evidence that National Broadcasting Company claims copyright on the television show.
Note that it may still be copyrighted in jurisdictions that do not apply the rule of the shorter term for US works (depending on the date of the author's death), such as Canada (70 years p.m.a.), Mainland China (50 years p.m.a., not Hong Kong or Macao), Germany (70 years p.m.a.), Mexico (100 years p.m.a.), Switzerland (70 years p.m.a.), and other countries with individual treaties.
