videophone(VIDEO telePHONE) A device with a camera and screen for visual, real-time communications, commonly known as "video calling." After AT&T debuted its Picturephone at the New York World's Fair in 1964, many expected videophones in the near future. Some 30 years later, AT&T introduced its VideoPhone-branded line at $1,000 per phone. Other vendors entered the market, but the bandwidth limitation of dial-up phone lines and the high cost of entry kept them from taking off.
Forty Years After the World's Fair
Due to high-speed cable and DSL, videophoning eventually became popular on the computer via software. Offering free video calling worldwide in 2006, Skype popularized the experience, and within a few years, Apple and Android phones and tablets would usher in a new world. See video calling, Webcam, Skype, videoconferencing and Picturephone.
|An Early Videophone|
|Throughout the 1990s, several companies promoted videophones, but squeezing real-time video over analog phone lines was dreadful. This ViaTV from 8x8 produced respectable quality as long as nobody moved; otherwise the image would pixelate. Subsequent 8x8 models used cable modems and DSL. (Image courtesy of 8x8, Inc.)|
