Videotelephony in the 21st century as imagined in 1910

Today in 1924, AT&T demonstrated long distance telephotography, now known as fax, with the transmission of pictures over telephone wires between Cleveland and New York. Commercial service began in a handful of cities the following year. For many decades, telephotography had one major use — sending photos of distant events for use by newspapers. Also today, in 1932, John Logie Baird demonstrated the Visiophone in Paris, France, a telephone capable of transmitting both audio and video.
