Microsoft has rebranded its online service Xbox Live to Xbox network so it wouldn't get confused with Xbox Live Gold.
"'Xbox network' refers to the underlying Xbox online service, which was updated in the Microsoft Services Agreement," a Microsoft spokesperson said. "The update from 'Xbox Live' to 'Xbox network' is intended to distinguish the underlying service from Xbox Live Gold memberships."
The name change was rumoured last year, but at the time Microsoft said it had no plan to do so.
Xbox Live Gold is Microsoft's premium multiplayer online service, which also gives access to discounts and two free games a month.
