Further information: "Video relay service
Significant improvements in "video call quality of service for the "deaf occurred in the United States in 2003 when "Sorenson Media Inc. (formerly Sorenson Vision), a video compression software coding company, developed its VP-100 model stand-alone videophone specifically for the "deaf community. It was designed to output its video to the user's television in order to lower the cost of acquisition, and to offer remote control and a powerful "video compression codec for unequaled video quality and ease of use with a video relay service (VRS). Favourable reviews quickly led to its popular usage at educational facilities for the deaf, and from there to the greater deaf community.
Coupled with similar high-quality videophones introduced by other electronics manufacturers, the "availability of high speed Internet, and "sponsored video relay services authorized by the U.S. "Federal Communications Commission in 2002, VRS services for the deaf underwent rapid growth in that country.

- ^ Although the pseudonymous letter was accompanied by a technical description of how the telectroscope would work and was published in a reputable New York newspaper, researchers later noted that it was published close to "April Fools Day and believed the article was submitted as an elaborate hoax.
- ^ One such demonstration that likely omitted any signal compression was performed in Mobile, Alabama on April 27, 1938. An Alabama news article reported that a "...technician of the American Television Institute, [promoted a videophone from a display booth for] the Roche Home Equipment Company... and through the medium of a scientific marvel... flashed a living picture over an ordinary telephone wire. Forming a practical insight into things that are to come, the television contrivance afforded a small, but clear, picture of speakers at each end of the wire."
- ^ Several uses of the Picturephone were novel and ahead of their time. At Alcoa in Pittsburgh, their Picturephone system was integrated into the company's corporate "Information Technology system under its APRIS, or Alcoa Picturephone Remote Information System. APRIS let users retrieve information from Alcoa's databases, controlled by the buttons on their "touch-tone telephones, with the data being presented on their Picturephone's video display, long before computer monitors came into popular use. AT&T's Bell Labs would also soon experiment with multiple users on the same videocall, creating one of the earliest forms of "videoconferencing.
- ^ The $500M figure is attributed only to the AT&T and Bell Labs' 15 year program covering its Picturephone Mod I and Mod II versions. Earlier videotelephony programs during the later half of the 1920s, the 1930s, late-1940s and the 1950s, plus the AT&T VideoPhone 2500 model program of the late-1980s led to a cumulative cost which approached, by some estimates, one billion dollars in total for all videotelephony development.
