Firestone sponsored a related television series, The Voice of Firestone Televues, one of the first television series with programming other than news or sports coverage, and according to researchers of television history, may have been the first regularly scheduled series in U.S. television history broadcast beyond New York on a network of multiple stations. It began on November 29, 1943 on New York's WNBT, when there were only a few thousand sets in existence. First seen on the rudimentary NBC television network in April 1944 (New York, Schenectady and Philadelphia), it continued until January 1947 with special interest topics in a documentary film format. "The Voice of Firestone" radio-TV programs were known not only for classical music, but for their support of organizations such as 4-H and the United Nations.
