A teleconference where non-voice information, such as PC data, text, images, PowerPoint presentations, and graphics, are shared in a teleconference. The term is synonymous with Web conferencing, and even audiographics. The term was first used in the 1990s when the ITU recommended the T.120 standard for sharing data during a teleconference.
