INVENTION OF BLUETOOTH!!!!

History
Harald I Bluetooth was the King of Denmark between 940 and 985 AD. The name "Blåtand" was probably taken from two old Danish words, 'blå' meaning dark skinned and 'tan' meaning great man. He was born in 910 as the son of King Grom The Old  and his wife Thyre Danebold. 

Why is It Called Bluetooth?

The developers of this wireless technology first used the name "Bluetooth" as a code name, but as time past, the name stuck.

The word "Bluetooth" is taken from the 10th century Danish King Harald Bluetooth. King Bluetooth had been influential in uniting Scandinavian Europe during an era when the region was torn apart by wars and feuding clans.

Where Did the Logo Come From?                                          

A Scandinavian firm originally designed the logo at the time the SIG was formally introduced to the public. Keeping to the same origin as the Bluetooth name, the logo unites the Runic alphabetic characters "H", which looks similar to an asterisk, and a "B", which are the initials for Harald Bluetooth. If you look close enough you can see both embodied in the logo.
