You’ve probably heard the story of 10th Century Danish King, Harald Blåtand, as it relates to Bluetooth, right? He was renowned connoisseur of blueberries; at least one of this teeth was permanently stained blue; yadda yadda yadda. What you might not know is that the Bluetooth symbol is actually a combination of the two runes that represent Harald’s initials.
It just so happens the first Bluetooth receptor also had a “teeth-like” shape, and was-you guessed it-blue.
But the symbolic interplay doesn’t end there. As the Bluetooth SIG notes, Blåtand “was instrumental in uniting warring factions in parts of what are now Norway, Sweden, and Denmark – just as Bluetooth technology is designed to allow collaboration between differing industries such as the computing, mobile phone, and automotive markets.”
