RTMark is a group of artist-activists promoting the creative subversion of corporate power. Its core is an Internet database of publicly-submitted projects that use humor and cleverness to convey important issues to very broad audiences. RTMark promotes successfully accomplished projects with carefully targeted press releases, much as corporations promote new products.

"The principle that organizes RTMark is that of collaboration. Internally, we collaborate to the fullest extent possible under physical law. Externally, we collaborate with journalists to bring issues that matter to an audience of millions of people. That audience, in turn, is our biggest collaborator in all of our projects—abstractly, concretely, and with an eye to the future."
