People believe Sky shouldn't be regulated as it's a private company unlike BT , Royal Mail etc , however Microsoft in the states is a private company and look at all the times they've been regulated or made to change things ( ever noticed on Windows now you have the choice of browser to install). Sky uses it's Market position to dictate the pay tv Market.

Would bundling together be the case if News Corp buys 100% of Sky (Ie selling newspaper subs with Sky and vice versa.)
