This may have gone around already, but the New York Times has an interesting story detailing a novel use of the DMCA. According to the NY Times, information about post-Thanksgiving sales was detailed on various online coupon Web sites prior to the date of intended release. This made the retailers (Wal-Mart, Target and others)angry, so they threatened the websites using the DMCA as the muscle behind their argument. However,

The Supreme Court has ruled that telephone white pages directories, for instance, do not fall within copyright law.
