The name Bluetooth comes from the Scandinavian word Blåtand/Blåtann, which originated from Harald "Bluetooth" Gormsson I, from Denmark and parts of Norway. He was a king, reined in the tenth century and united discordant Danish tribes into a single kingdom. Bluetooth established the name to indicate that they united communication protocols into one universal standard.
