An information service in which data is transmitted over television cables or telephone lines and displayed on a television or computer screen.
Any of various early electronic systems for the distribution of data for display on video screens, often allowing for input by the user.
The first attempts at interactive information delivery for shopping, banking, news, etc. Many trials were made, but it never caught on in the U.S. and was not very successful anywhere except in France (see Minitel). Videotex uses a TV set-top box and keyboard. Data are delivered by phone line and stored in the box as predefined frames with limited graphics that are retrieved by menu.
