On September 14th at 10pm EST in the US (tonight), a new experiment in television will take place that is both a sign of the times, and a quiet revolution in the way that broadcast TV (and perhaps media itself) will work. The Jay Leno Show will debut at its new time slot of 10pm - a full hour and a half earlier than he used to be on when doing The Tonight Show - and aim to reach people "exhausted by kids, work and so on" as he has said more than once in interviews. The significance of this moment is not so much about the change in time - but in what types of programs he will be up against.

Englewood, Colo. - Satellite TV firm DISH Network (NASD: DISH) and sister company EchoStar (NASD: SATS) announced on Wednesday that the U.S. Patent and Trademark Office has agreed to re-examine the validity of TiVo's (NASD: TIVO) core digital video recorder technology patent.

Washington - The U.S. Supreme Court has asked the federal government to submit an opinion on Cablevision's (NYSE: CVC) proposed network-based digital video recorder, which drew a lawsuit from movie studios and television networks that is currently under appeal, Reuters reported. The U.S. Court of Appeals ruled that such a device -- which would "store" the programs a user chooses to record on Cablevision's servers, rather than on a hard drive-based device like a TiVo -- would not directly infringe the copyrights of media companies.
