A Perspective on the Development of Videotex

1. The twentieth century has seen the emergence of the information age¹. The telephone, radio, motion pictures, television, and the computer all have had profound effects upon our life style and all are concerned primarily with the communication or storage of information. Information has become a commodity to be produced and traded. The pace of technological development is quickening. The cost of communications and information storage is rapidly decreasing and the whole structure of the information industry is constantly changing. The only thing that can be depended upon is that change will occur. To help manage this need for creation and dissemination of information a new interactive electronic system, videotex, has evolved.

2. Videotex is a name used internationally to represent a class of home and business information services which disseminate information from public information suppliers into the home or office. In the domestic situation the home television receiver, suitably modified would serve as the consumer's terminal equipment. The system essentially makes use of² the home television set as a picture display medium in which the consumer has control over what is displayed. An electronics module is added to the home television set to allow us to assemble and display an image made up of characters and graphics drawings. By utilizing the common-carrier telephone line or other interactive network or broadcast system, users of videotex services will be able to retrieve information stored in computer-controlled databases and have it displayed on their augmented TV receivers or video business terminals. They will be able to access textual information or graphic images from centralized public or private data banks. Individuals with slightly more complex terminals will be able to compose their own information to be stored in the data banks for access by others. As mass production reduces the cost of producing electronic components, individuals will be able to communicate with each other and interact by being able to see the same images displayed on their individual television screens. These various capabilities, which bring advanced technologies to the home user, could have a profound effect on communications and in our society. Such systems allow the introduction of many different services for home and business applications.
