What is Bluetooth?
Bluetooth is a wireless technology standard for exchanging data over short distances using radio waves. The technology was created by the Swedish telecom company Ericsson in 1994, and is named after the tenth-century Danish king Harald I, nicknamed Harald Blåtand (“Blue tooth” in English). An Ericsson employee was reading The Long Ships at the time – an historical novel about the Vikings and King Harald Bluetooth. The king is credited with uniting independent Danish tribes into one kingdom – as Bluetooth technology united wireless communication protocols into one universal standard. The Bluetooth logo is a Viking-era rune, combining the letters ‘H’ and ‘B’ for “Harald Bluetooth.” Read more on Wikipedia.
