This television set, retailing for $100, is reportedly the first moderately priced receiver manufactured in quantity. Rose Clare Leonard watches the screen, which reproduces a 5x7 image, as she tunes in at the first public post-war showing at a New York department store, on August 24, 1945. Although television was invented prior to World War II, the war prevented mass production. Soon after the war, sales and production picked up, and by 1948, regular commercial network programming had begun.
This 1946 photograph shows ENIAC (Electronic Numerical Integrator And Computer), the first general purpose electronic computer - a 30-ton machine housed at the University of Pennsylvania. Developed in secret starting in 1943, ENIAC was designed to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory. The completed machine was announced to the public on February 14, 1946. The inventors of ENIAC promoted the spread of the new technologies through a series of influential lectures on the construction of electronic digital computers at the University of Pennsylvania in 1946, known as the Moore School Lectures.
