There are going to be some changes in Blizzard online games. Battle.net, which was created in 1996 to allow online gameplay in the first Diablo and all later games released by Blizzard will change it's name. Blizzard believes, that sometimes there is a consufion related to the name Battle.net, apparently Blizzard and Battle.net were identified as separate companies. The new name of the service will include the word Blizzard, however, the core and functionality is meant to stay the same. The changes will be implemented within a few months which we are still to be informed about.
We’re going to be transitioning away from using the Battle.net name for our gaming service and the functionality connected to it. Battle.net technology will continue to serve as the central nervous system for Blizzard games—nothing is changing in that regard. We'll just be referring to our various products and services using the Blizzard name instead. You've already seen this recently with things like "Blizzard Streaming" and "Blizzard Voice," and more changes are on the way.
When we created Battle.net, the idea of including a tailored online-gaming service together with your game was more of a novel concept, so we put a lot of focus on explaining what the service was and how it worked, including giving it a distinct name. Over time, though, we’ve seen that there’s been occasional confusion and inefficiencies related to having two separate identities under which everything falls-Blizzard and Battle.net. Given that built-in multiplayer support is a well-understood concept and more of a normal expectation these days, there isn’t as much of a need to maintain a separate identity for what is essentially our networking technology.
We just wanted to make sure everyone was aware as we moved forward with this change over the next several months; we’ll provide any relevant updates as the transition progresses.
