Today in 1927, a group of newspaper reporters and dignitaries gathered at the AT&T Bell Telephone Laboratories auditorium in New York City to see the first American demonstration of something new: television. Secretary of Commerce Herbert Hoover provided the “entertainment,” as his live picture and voice were transmitted over telephone lines from Washington, D.C., to New York. “Today we have, in a sense, the transmission of sight for the first time in the world’s history,” Hoover said. “Human genius has now destroyed the impediment of distance in a new respect, and in a manner hitherto unknown.”
