The Motion Picture
In 1922, engineers and scientists at the University of Illinois, Urban- Champaign invented the sound motion picture. The first public demonstration of sound recorded simultaneously with pictures on film took place at the Urbana campus on June 9, 1922. Joseph T. Tykociner’s double-feature motion picture included ringing a bell and reading the Gettysburg Address. The invention was not patented. The first commercial talking film in 1927 used a phonograph, and Tykociner’s invention was only later recognized. It is still used for sound on film.
