It’s estimated that there are over 30 million Bluetooth devices in the world today. But why is it called Bluetooth?
The name Bluetooth is derived from a 10th-century Scandinavian king, Harald “Blatand” Gormsson. King Harold united Denmark and Norway. He was also known for his love of blueberries, which gave him his nickname “Blatand.”
In 1997, Jim Kardach from Intel and Sven Mattisson from Ericsson, were working on a short-range wireless link for laptops and mobile phones. They wanted a name that would be easy to pronounce in multiple languages and would reflect their vision for the technology.
So they came up with the name Bluetooth, which was inspired by King Harold’s nickname. The Bluetooth logo is also a combination of the two Scandinavian runes for H and B.
The short answer is that they were trying to avoid trademark infringement issues with Ericsson, who were using a similar technology and had a trademark on their name.

It is fast, it is completely wireless, it lets you can connect your phone, your phonebook, your MP3 player and more.
The name bluetooth is a combination of two Danish words: “Blåtand” and “Hans”. Blåtand is the Danish name for King Harald Bluetooth, who ruled Denmark from around 958 to 985 AD. Hans was Harald’s nickname.
Bluetooth was originally developed as a wireless system to replace cables between devices, like cell phones and laptops.
