Why is bluetooth called bluetooth?
Origin of the name and the logo Bluetooth was named after a late 900s king, Harald Bluetooth King of Denmark and Norway. 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 likewise was intended to unify different technologies, such as computers and mobile phones. The name may have been inspired less by the historical Harald than the loose interpretation of him in The Long Ships by Frans Gunnar Bengtsson, a Swedish Viking-inspired novel. The Bluetooth logo merges the Nordic runes analogous to the modern Latin H and B: (haglaz) and (berkanan) forming a bind rune.
The name Bluetooth was born from the 10th century king of Denmark, King Harold Bluetooth who engaged in diplomacy which led warring parties to negotiate with each other. The inventors of the Bluetooth technology thought this a fitting name for their technology which allowed different devices to talk to each other.
