1Case, D.O.: ¬The social shaping of videotex : how information services for the public have evolved.
In: Journal of the American Society for Information Science. 45(1994) no.7, S.483-497.
Abstract: 'Videotex' was an early incarnation of what have been more recently called 'end-user information services'. This article considers the origins and historical development of videotex over three decades, comparing various nationally sponsored and private systems in Europe and North America, and discussing reasons given for the 'failure' of videotex. The influence of nontechnical factors on videotex and perceptions of critical problems and acceptable solutions are described. According to this interpretation, the development of videotex faced four 'bottlenecks' at once: the determination of transmission channels; the choice of a display device; agreement on coding standards; and the marketing of these resulting services. In how it accomodated these problems, videotex provides an example of how social, political, and economic elements are inseparable from technical constraints in the development of new information technologies

4Black, G.: Videotex at the crossroads.
In: Information management report. 1993, Sept., S.10-12.
Abstract: Discusses the present situation of videotex in the UK, where it is known as Prestel, and in France, where it is called Minitel, with brief reference also to the USA, Germany and other countries. Notes plans in both the UK and France to introduce systems which may replace it for many users. Argues that despite the noted success of videotex in France, the prospects for its growth generally are not encouraging. Puts this in the context of the shift away from telecommunications monopolies

5Hattery, M.: Videotex in the US in 1991.
In: Information retrieval and library automation. 27(1991) no.4, S.1-4.
Abstract: Videotex systems have failed to penetrate significantly into the US market. Services such as home shopping, airline schedules and sports scores do not provide the necessary 'single critical service'. Electronic mail, messaging and community bulletin boards generate the most usage. Lack of open platforms and competition has led to poor services and hardware presents a barrier to everyman use. Describes services provided by US videotex companies Compuserve, Prodigy, American Online, Delphi and GEnie as well as smaller local commercial and non-commercial services. Videotex can be valuable for the physically handicapped, senior citizens, and health services

6Forster, B.: Public access videotex terminals : HARVIE's experience.
In: Information media and technology. 24(1991) no.3, S.108-109.
Abstract: Harlow Viewdata is a viewdata service of 9 public access terminals provided by Harlow District Council Advice Centre, UK which dealt with over 3.000 queries in its 1st year of opration. Outlines the experience of setting up a local authority viewdata service and describes Datavision, Innovative Videotext and Metrotel viewdata terminals. Maintenance charges are expansive for terminals, therefore paying one-off call out charges are most economical. It is difficult to keep viewdata systems up-to-date and when setting up a service it is advisable to ensure that staff and others concerned are fully aware of their roles
