The weird Bluetooth logo is really the initials of Danish King Harold Bluetooth, the tech’s namesake
Bluetooth is one of the modern age's most wonderful technologies. You might be surprised to know that it was named after a King from a very long time ago. The name comes from Ericcson's—Bluetooth's parent company—Viking heritage.
Legend says that Danish Viking Harald Blatand had a gift for bringing people together and fostering communication. He even united Norway and Denmark as a single territory.
So, since Bluetooth is intended to connect people and allow them to communicate easily, what better person to name it after then Blatand? In English, Blatand translates to "Bluetooth."
