Media law now has legs and wheels. Mobile devices create new challenges for media law. Can the content be re-purposed to the new media platform? The answer, by the way might be “no,” because it depends upon the rights that the distributor has. See NY Times v. Tasini for a case where the content distributor (NYT) should have gotten more rights for new technology distribution. What about services that pick up signals transmitted over-the-air and make them available on the Internet? What about making your own ringtones? Are those copyright infringement? How about books? Books used to be print items, but now e-books are taking over. All of these create new challenges for media lawyers and media entrepreneurs.
