The BattleTag is a player-created name that serves as your Battle.net title. It is used in all Blizzard games, as well as on their forums and community websites. Players create a name of up to 12 characters, and this becomes their official title on Battle.net. Your BattleTag is what other players see on your Diablo III characters, and what appears on their Friends List.
A digital camera records and stores photographic images in digital form. Many current models are also able to capture sound or video, in addition to still images.
The first recorded attempt at building a digital camera was in 1975 by Steven Sasson, an engineer at Eastman Kodak. It used the then-new solid-state CCD (charge-coupled device, a high-speed semiconductor) image sensor chips developed by Fairchild Semiconductor in 1973.
