This pamphlet was published "upon the occasion of the first public demonstration of television in Ohio".  This demonstration was presented with the cooperation of RCA Victor and was held at the H. & S. Pogue Department Store in downtown Cincinnati, September 18-23, 1939.  The text describes the many scientific discoveries that led to the development of television.  It also discusses Cincinnati's interest in this new medium and cites the Crosley Corporation's application for a license to televise, which was then awaiting FCC approval.  The demonstration  utilized announcers and entertainers provided by Crosley radio stations WLW and WSAI.
