Book excerpt: Beginning with Thomas Edison's aggressive copyright disputes and concluding with recent lawsuits against YouTube, Hollywood's Copyright Wars follows the struggle of the film, television, and digital media industries to influence and adapt to copyright law. Though much of Hollywood's engagement with the law occurs offstage, in the larger theater of copyright, many of Hollywood's most valued treasures, from Modern Times (1936) to Star Wars (1977), cannot be fully understood without appreciating their legal controversies. Peter Decherney shows that the history of intellectual property in Hollywood has not always mirrored the evolution of the law and recounts these extralegal solutions and their impact on American media and culture.
