query: What factors contributed to the rise in rates for the new channel agreement between Sky and Virgin Media in 2007?
answer: Sky attributed the rate increase to the inclusion of Sky3, Sky Arts, and undisclosed high-definition and video-on-demand content in the new deal.  Virgin Media, however, argued that a minimum payment guarantee in the contract meant the actual cost would be more than double the current payment.
