Here is a quick bit of background on this one. A lot of you in the UK may already have a Sky+HD from Sky or a V+ HD box from Virgin media. The thing that they have in common is that they both allow you to record TV shows. In some cases, some of the TV channels also show some decent films from time to time. The main reason that I use my Sky+HD box is to record shows and watch them without having to sit through any adverts.
Over in the USA three of the major broadcasters(FOX, NBC and CBS), are suing Dish Network(a major US TV provider) over one of their DVR(digital video recorders). Known as the Hopper, it would allow users to automatically skip over ad breaks which interrupted shows which they had recorded.
The lawsuits of the TV networks, which were filed individually, allege that the ad hopping is illegal because it involves the gadget making an unauthorised version of a copyrighted TV show.
