An article about copyright protection for digital entertainment venues includes comments by WSU law professor Jessica Litman, an expert on copyright law. She is the author of the book "Digital Copyright." The copyright controversy centers around peer-to-peer file sharing, which is driving entertainment companies toward increased control of content. The article points out that media companies are lobbying for laws that are friendlier to the rights of content owners and that Hollywood is threatening to withhold access to its libraries unless electronics manufacturers build devices with sufficient copy protection. "Copyright law was intended to protect reading, viewing and listening" Litman says. "Now it takes what people previously saw as their rights and treats them as loopholes the copyright owners will close if they can."
