Virgin also do also use Sky networks for some of their movie platform, too. Like BT have their premium sports, Sky have their sports, and cinema too - does Virgin have anything comparable on either?

That being said BT have the main advantage which is that every third party supplier of internet / wireless services that is not copper / optic based like VM has to use BT / Openreach's hardware - like Sky, Talk talk etc. Unless VM allows other providers to operate on its network (which I am unaware of) BT has a huge advantage.

Inadvertently (without mean to), you kind of made Denphone's point, by mentioning Talk Talk / third party providers that use BT's hardware.
