IT is used by everyone with smartphones and has been a household name for 28 years.
But although most people have heard of Bluetooth, few know the curious story behind its name and logo.
It turns out that the term is named after a Norse ruler who reigned many centuries ago.
King Harald “Bluetooth” Gormsson unified Denmark and Norway in the 10th century and apparently took his nickname after his dead tooth, which is dark blue/gray.
His alternate moniker is said to be in keeping with the new piece of technology when it was created in the ’90s.
It was chosen because King Harald brought the two nations together – because the technology was designed to do with electronic devices.
Bluetooth allows information and data to be transferred from one device to another over a short range without the need for a physical connection.
Today, it’s what connects your smartphone to headphones and other wireless devices.
Originally, Bluetooth was intended as an internal codename while the technology was being fully developed.
However, when the other choices presented by the marketing team were either too unoriginal or could not be patented in time for release, the engineers settled with what they had.
The Bluetooth logo is a combination of King Harald’s initials in “runes”: ᚼ (Hagall) and ᛒ (Bjarkan).
King Harald lived in the 10th century and is famous for introducing Christianity to Scandinavia.
At one point, he ruled over what is now Denmark, northern Germany, southern Sweden, and parts of Norway.
While some accounts claim that his blue skinner gave him his nickname, it may actually come from the color of his skin.
Apparently, “Blaa” is the modern Danish word for “blue”, but in the old days meant “dark skin”.
On the other hand, “Tan” used to mean “great person”, but has been confused with the modern Danish word for “teeth”.
