Tim McKenna is an author who thinks and writes about the complexity of truth in a world of flux. He wrote in October 2000: "Copyright is a difficult issue. The owner of the intellectual property thinks that s/he owns what s/he has created. I believe that the consumer purchases the piece of plastic (in the case of a CD) or the bounded pages (in the case of book). The business community has not found a new way to add value to intellectual property. Consumers don't think very abstractly. When they download songs for example, they are simply listening to them, they are not possessing them. The music and publishing industry need to find ways to give consumers tactile vehicles for selling the intellectual property." = Copyright and WIPO Since the web became mainstream, the posting by the thousands of electronic texts and other documents has been an headache for organizations in charge of applying the rules relating to intellectual property. The World Intellectual Property Organization (WIPO) is an intergovernmental organization, and one of the 16 specialized agencies of the United Nations. It is responsible for protecting intellectual property throughout the world through cooperation among countries. It is also responsible for implementing various multilateral treaties dealing with the legal and administrative aspects of intellectual property. Intellectual property comprises industrial property and copyright. Industrial property relates to inventions, trademarks, industrial designs and appellations of origin. Copyright relates to literary, musical, artistic, photographic and audiovisual works. WIPO stated on its website in 1999: "As regards the number of literary and artistic works created worldwide, it is difficult to make a precise estimate. However, the information available indicates that at present around 1,000,000 books/titles are published and some 5,000 feature films are produced in a year, and the number of copies of phonograms sold per year presently is more than 3,000 million."
