October 5 – The first telecast of a presidential address from the White House. President Truman speaks about the world food crisis. It is preceded by a Jell-O commercial, and features the president discussing his program for food rationing. The address was televised by WTVW-TV (presently WJLA-TV Channel 7 in Washington DC) as part of its inaugural broadcast. It was also simulcast by radio. It was long believed that no copy of this broadcast existed, but segments are preserved on kinescope in the Library of Congress. (For the record, President Franklin Roosevelt's address broadcast over NBC experimental television W2XBS -- now WNBC -- at the 1939 New York World's Fair preceded the 1947 Truman broadcast. However, Truman's broadcast is indeed the first from inside the White House.)
