The first public videoconference was held in April 1930, between AT&T headquarters and their BellLaboratory in New York City. [Rosen] Microphones and loudspeakers transmitted the audio while,under a blue light, their images were captured and transmitted as they looked into photoelectric cells. An article in the April 10 edition of the New York Daily Mirror described the audio as clear and the image as inoffensive (a term commonly used for driver's license photos but not often heard today for videoconferencing!) It was at this time that the value of face-to-face conversation at a distance was expressed.
