Videotelephony

Real-time video communication

Videotelephony, also known as video chat, videoconferencing, video calling, or telepresence, is the use of audio and video for simultaneous two-way communication. Videophones were standalone devices for video calling (compare Telephone). As smartphones and computers have become capable of video calling, the demand for a separate category of videophones has disappeared.
