MEDIA l is a pla~orm that allows the commercialization and dissemination of electronic documents under similar conditions as printed documents using an agent-based, distributed and secure platform.

The developed pilot application of MEDIA is HyperNews, a commercial electronic newspaper environment allowing its readers to buy articles from different information providers (electronic newspaper publishers) and compose their own personalized newspaper.
