What modern invention has had as great of an effect on the spread of knowledge in our society as the printing press did on Renaissance society? Why?

Well my response to the question is that the printing press revolution in human communications is happening. But People around the world are connecting to each other via the new computer telecommunication networks now known as the Net. The Net, in a significant way, is a continuation of the important technological development of the printing press. The printing press might seem to be a choice for such a comparison considering the similarity that might be seen between the Net and, for example, Television's and the telephone, radio, or the news media.
