“Bluetooth” technology was named after a 10th-century king, King Harald “Bluetooth” Gormsson. He united Denmark and Norway, just like the technology united computers and cell phones.

The story behind the naming of Bluetooth technology dates back to the late 1990s. In 1996, Jim Kardach, an engineer at Intel, was working on a project to develop a short-range wireless communication standard. To create a memorable name for the technology, he drew inspiration from King Harald “Bluetooth” Gormsson, who ruled in the 10th century.
King Harald, who reigned from around 958 to 986 AD, is known for uniting tribes in Denmark and Norway, much like how Bluetooth aimed to unite various devices, such as computers and mobile phones. The idea was to create a standard that would enable seamless communication between devices, which was a significant innovation at the time.
The Bluetooth Special Interest Group (SIG) was formed in May 1998, and the technology was officially launched in 1999. The connection to King Harald served as a symbolic reminder of unity and collaboration in the tech world. The Bluetooth logo incorporates the initials of the king in runic form, further solidifying the historical connection.
