The History of Bluetooth The name Bluetooth comes from the name of a king, King Harald Blatand (translated Harold Bluetooth) of Denmark and Norway from 935-940 A.D. He is known for his unification of previously warring tribes from Denmark (including Scania, present-day Sweden, where the Bluetooth technology was invented) and Norway.

Bluetooth was intended to unify different technologies like computers and mobile phones. The name is inspired by the historical King Bluetooth, who united the Scandinavian countries. The Bluetooth logo merges the Nordic runes analogous to the modern Latin H and B: (Haglaz) and (Berkanan).
