John Blossom at Shore Communications has an interesting post on Digital Rights Management and how this often maligned technology is “no longer a capability that premium publishers can afford to avoid.” I think it depends on the publisher and what they’re publishing. In the business information space, the majority of premium information used on a daily basis has a very short shelf life and is only of interest to a handful of people working on a particular deal or project. It’s not like a song or a movie, which has a much longer shelf life and may be of interest to many people over an extended period of time. The exception, of course, is an expensive market research report that is published say, annually, where restrictions on use makes economic sense for the publisher.
