Reproduction of copyrighted works is permitted without payment of royalties under the fair use doc­trine. The factors used in determining whether a use qualifies as fair are (1) the purpose and character of the use, in­cluding whether it is of a commercial nature or is for nonprofit educational purposes; (2) the nature of the copy­righted work; (3) the amount and substantiality of the portion used in relation to the work as a whole; and (4) the effect of the use on the potential market for or value of the copyrighted work.  In light of the broad availability of the Internet, should the Fair Use Doctrine be changed?  What impact do you think such would have on the willingness of potential copyright owners to seek copyright protection?
