INFORMATION TO USERS This was produced from a copy of a document sent to us for microfilming. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help you understand markings or notations which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page{s)”. If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure you of complete continuity. 2. When an image on the film is obliterated with a round black mark it is an indication that the film inspector noticed either blurred copy because of movement during exposure, or duplicate copy. Unless we meant to delete copyrighted materials that should not have been filmed, you will find a good image of the page in the adjacent frame. If copyrighted materials were deleted you will find a target note listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photo graphed the photographer has followed a definite method in "sectioning" the material. It is customary to begin filming at the upper left hand corner of a large sheet and to continue from left to right in equal sections with small overlaps. If necessary, sectioning is continued again-beginning below the first row and continuing on until complete. 4. For any illustrations that cannot be reproduced satisfactorily by xerography, photographic prints can be purchased at additional cost and tipped into your xerographic copy. Requests can be made to our Dissertations Customer Services Department. 5. Some pages in any document may have indistinct print. In all cases we have filmed the best available copy.

Wayne Talarzyk Advisor 0 COPYRIGHT WILLIAM THEODORE BOLTON 1981 THE PERCEPTION AND POTENTIAL ADOPTION OF CHANNEL 2000: IMPLICATIONS FOR DIFFUSION THEORY AND VIDEOTEX TECHNOLOGY By William Theodore Bolton, Ph.D. The Ohio State University, 1981 Professor Thomas McCain, Advisor The dissemination of computerized information into the home, via interactive home information systems, has been characterized as a revolutionary technological innovation which will affect the way people work, and how they conduct their daily lives. This research examined one form of this technology during a three month field test of a proto type viewdata system called Channel 2000. Channel 2000 as an electronic informational device, delivered library and banking services, in addition to various types of community information, to 71 randomly selected Columbus, Ohio households. Users had free and unlimited access to these electronic services throughout the field test. Diffusion theory served as the theoretical model which guided the questionnaire development and data interpretation procedures used in this research. According to diffusion theory, the perceived attributes of an innovation can to a certain extent, determine whether an innova tion such as Channel 2000, is either accepted or rejected. In an effort to assess the degree to which these perceptions, and other life style, personality, and socio-demographic measures could discriminate between iii potential adopters and non-adopters of Channel 2000, a series of three stepwise two-group discriminant analyses were completed. .. Three significant discriminant functions were derived using each of these measures before, during, and after the test. The innovation perceptions consistently demonstrated the most discriminatory strength among all other measures. The perceptions themselves also indicated that although Channel 2000 was perceived as being not complex, users felt that it offered them few advantages, and that it was not very compatible with their current experiences, values, or needs. The results of this study suggested that innovation perceptions may be a very useful discriminatory tool, as well as a helpful device in the development of future home information systems. Other recommenda tions for future research, and the implications for diffusion theory and videotex technology which resulted from this research, are presented within the discussion of the findings. All questionnaire items and frequency tabulations are also included as Appendices. ACKNOWLEDGMENTS The Channel 2000 project represented the combined efforts of many individuals.
