ABSTRACT
As the 21st century enters its fourth year, nations throughout the world continue to make significant investments in technology for homes, schools, and workplaces. In some cases, technological advances have supplanted older technologies. For example, modern teenagers believe that CD or MP3 players are the only means to listen to music, as they have had little to no exposure to vinyl records and turntables, or to cassette tapes and tape players. In a similar vein, in the United States, DVD players are fast overtaking VCRs as the means to view movies in the home. Although new technologies sometimes replace older technologies, new technologies often coexist with previously developed and older technologies. For example, despite the availability of electronic versions of newspapers, magazines, and journals, “hard” copies continue to be bought, sold, and read in homes, libraries, and places of business.
