T322: Video Communications/telephony 30 November 2010 Video Communications: A Telephony Fiasco On the surface, it may have seemed like the idea of a visual telephony communications system, which enables individuals to not only hear, but also to see the other party through the telephone, would have been an innovation bound for success. To the surprise of many, the outcome of this invention turned out to be a failure, which led to various investigations and studies as to why this may have occurred.

attempts by large corporations to sell these products have generally failed (Kraut 438). According to Noll, author of the book Introduction to Telephones and Telephone Systems , a study done in 1974 indicated that users of the Picturephone service would not care if it were to be discontinued. Another study conducted that focused on teleconferencing indicated that even when the service was offered to customers for free, they still had no
