Several months ago Dish Network unveiled a slick new DVR that had some very interesting features that allow you to skip all commercials on prime time programming. The commercial skipping tech was called AutoHop and it worked in conjunction with PrimeTime Any time to allow you to automatically remove commercials from primetime programming on the four major networks.
Those commercials were completely removed and the programs were stitched back together so you didn't even have to use fast-forward. That didn't set well with television studios who filed suit against Dish trying to ban the feature on grounds of copyright infringement and other things. However the court has ruled For Dish Network on all charges finding that there is no copyright infringement or violation of federal laws with either feature.
