Abstract:

Very briefly, thin copyright usually refers to a minimalist approach to copyright, giving works only as much protection as is needed to encourage creativity but with a goal of making works readily available to the public. Thick copyright is a more maximalist approach, and crudely put the goal of thick copyright is generally to maximize profits. We appear to be moving toward thick copyright, not only in this county but around the world in general. This movement is being spearheaded, as you might expect, by companies whose main product is in the form of intellectual property, such as books, movies and music. But there is yet another trend relating to the protection of intellectual property and that is the creation of technological controls to protect digital works. This is referred to as Digital Rights Management, or DRM. DRM is not a single technology and it is not even a single philosophy. It refers to a broad range of technologies and standards, many of which are still in the planning and development stage. DRM is not thin copyright, and it isn't even thick copyright; DRM is potentially a nearly absolute protection of works.
