The history of American copyright law originated with the introduction of the printing press to England in the late fifteenth century. With the invention of the printing press works were getting very easy to steal and claim as ones own. But despite this being a problem for a long time was not addressed until 1787 when the U.S. Constitution was written and stated "the Congress shall have power . . . to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries." Then came the Copyright Act of 1790 which granted American authors the right to print, re-print, or publish their work for a period of fourteen years and to renew for another fourteen. Then a major revision of the U.S. Copyright Act was completed in 1909. The bill broadened the scope of categories protected to include all works of authorship, and extended the term of protection to twenty-eight years with a possible renewal of twenty-eight.
