According to Media Rights Technologies (MRT), all of them are infringing products under the Digital Millennium Copyright Act, and MRT has just sent cease-and-desist letters to Microsoft, Adobe, Real, and Apple. "Together these four companies are responsible for 98 percent of the media players in the marketplace; CNN, NPR, Clear Channel, MySpace, Yahoo, and YouTube all use these infringing devices to distribute copyrighted works," said MRT CEO Hank Risan in a statement. "We will hold the responsible parties accountable. The time of suing John Doe is over."
