VIDEOTEX refers to various computer-based interactive systems that
electronically deliver text, numbers and graphics via telephone lines,
two-way cable, computer networks, or any combination of the three, for
display on a television set, video monitor or personal computer.
Every interactive online system that has existed,
including the Internet, falls under the videotex umbrella.
- It is interactive,
meaning two-way communication is supported.
- Data is stored in
computers, often PCs, minicomputers, or mainframes.
- User can access the
data of choice either via a keyboard, dedicated terminal or computer.
- Menu-driven systems
allow users to browse, much like they do a newspaper.
- Command-line
interface allows very fast searches for specific data.
- Offers much better
graphics than teletext, even photo display.
- Messaging and
bulletin boards -- among the first truly interactive, participatory
services -- proved extremely popular, surprising operators.
- Latest and most
popular versions of videotex systems are America Online and the World
Wide Web.
