You must have heard of Bluetooth or most probably be using it by all means by now. Did you ever think why the concept was named Bluetooth? Well here is a snippet from Wikipedia on Bluetooth as to why it was named so.
“The name Bluetooth was born from the 10th century king of Denmark, King Harold Bluetooth (whose surname is sometimes written as Bluetooh), who engaged in diplomacy which led warring parties to negotiate with each other. The inventors of the Bluetooth technology thought this a fitting name for their technology which allowed different devices to talk to each other.“
Have a great week ahead.
