CBS Reality, Horror Channel, CBS Action, CBS Drama, CBS Reality +1 and Horror Channel +1 were available as a free promotional offer to all customers throughout April. These have now returned to their respective TV packs, as the broadcaster has a profit share agreement with Virgin where they take a cut of the subscription income from the packs they are on.
Virgin is after all a pay platform, & if broadcasters decide they want to make money out of joining it, they will.
