Excerpt: A videophone is a telephone with a video screen, and is capable of full duplex (bi-directional) video and audio transmissions for communication between people in real-time. It was the first form of videotelephony, later to be followed by videoconferencing, webcams, and finally telepresence. At the dawn of the technology, videotelephony also included image phones which would exchange still images between units every few seconds over conventional POTS-type telephone lines, essentially the same as slow scan TV systems. Currently videophones are particularly useful to the deaf and speech-impaired who can use them with sign language, and also with video relay services to communicate with hearing persons. Videophones are also very useful to those with mobility issues or those who are located in distant places and are in need of telemedical or tele-educational services. Newer units, such as this Avaya Nortel 1535 IP model, have migrated away from slow POTS lines to higher speed ISDN and broadband VoIP servicesThe name videophone never became as standardized as its earlier counterpart telephone, resulting in a variety of names and terms being used worldwide, and even within the same region or country. Videophones are also known as video phones, videotelephones (or video telephones) and often by an early trademarked name Picturephone, which was the world's first commercial videophone produced in volume. The compound name videophone slowly entered into general use after 1950, although video telephone likely entered the lexicon earlier after video was coined in 1935. Videophone calls (also: videocalls and video chat), differ from videoconferencing in that they expect to serve individuals, not groups. However that distinction has becoming increasingly blurred with technology improvements such as increased bandwidth and sophisticated software clients that can allow for multiple parties on a call. In general everyday usage the term videoconferencing is now frequently used instead
