Viking Facts

Bluetooth is named after the 10th-century Danish King Harald "Bluetooth" Gormsson. The wireless protocol was named after him because of his ability to unite warring Scandinavian factions, just as Bluetooth unites different wireless devices. The Bluetooth logo is a combination of the King's runic initials (ᚼ and ᛒ) merged together.

Iceland has been so culturally isolated through history since the Vikings, that compared to other Scandinavian counties, people who speak Icelandic can still read the old Norsk sagas.
