Bluetooth was named after Harald Bluetooth , the King of Denmark 1000 years ago.
Intel proposed that the SIG be called by the "codename" Bluetooth until the SIG's marketing group would come up with a formal technology name. When asked about the name Bluetooth, I explained that Bluetooth was borrowed from the 10th century, second King of Denmark, King Harald Bluetooth; who was famous for uniting Scandinavia just as we intended to unite the PC and cellular industries with a short-range wireless link.
