The Week: Media News - Sky in ad sales court battle

Discovery Networks UK is taking BSkyB to the High Court over a dispute about the companies' advertising sales contract.

Sky Media has sold advertising for Discovery's TV channels since 2006 and the current deal expires at the end of 2009. It is understood that the disagreement centres on a clause that allows Sky Media to cap the amount of money Discovery receives when its channels' commercial impacts reach a certain level.
