content producers-newspapers, book publishers, television, movie, and music producers-generate revenue and profits from their creations, and they protect these revenue streams through copyright. Created by Congress in Article I, Section 8 of the United States Constitution, Congress granted authors and inventors copyrights and patent rights to ''the progress of science and useful arts.'' The first Copyright Act was passed in 1790. In the digital age, when exact copies and widescale distribution of works are possible, protecting the copyrights to content is a major challenge.
