Designed to provide an overview of the nature and focus of activity in the fledgling videotex industry in the United States and Canada, this updated and extended report presents in-depth reviews of 26 projects which reflect the involvement of such industries as publishing, retailing, agriculture, banking, other financial intermediaries, information processing, broadcasting, and communications. Reviews were compiled from interviews conducted with one or more actively involved participants in each project, published information, and materials forwarded by respondents. Information provided for each project includes sponsor(s), technology, location, current status, investment, anticipated future services, subscriber base, availability, content providers, system characteristics, pricing, content information, and delivery system. Technologies used include internally developed viewdata systems, standard telephone lines, French Antiope-based teletext system, home terminals, Telidon-based viewdata and teletext systems, British Ceefax teletext system, and AT&T's Presentation Level Protocol. Some projects specialize in information for a specific audience, e.g., farmers, lawyers, or business men, while others offer a wide range of services which may include local and community information; entertainment guides; consumer information and advice; shopping, banking, and travel services; computer assisted instruction; and video games. Brief notes on other activities in the field are included. (LMM)
