Bluetooth Namesake

For those who like a bit of obscure knowledge to throw around at dinner parties, here's a little tidbit: Bluetooth technology got its name from a Danish king. That's right. The tenth-century Danish Viking King Harald Blatand (English translation of Blatand is literally "Bluetooth") is known throughout history for uniting Norway and Denmark under Christianity. Bluetooth technology unites different electronic devices without the use of cables or wires, hence the namesake. King Blatand was also known for his love of blueberries, which turned his teeth a displeasing bluish colour.
