Videophones were first conceptualized in the early 20th century, with significant development occurring in the 1920s and 1930s. The first public demonstration of a videophone was by AT&T at the 1964 New York World's Fair with their Picturephone service. However, practical and widespread use of videophones did not become feasible until the advent of digital technology and the internet in the late 20th and early 21st centuries.
