Bluetooth is named after King Harald Bluetooth who united Denmark and Norway. He had a dead tooth that was blue which is how he got his nickname. The bluetooth logo is made up of Harald's initials in Old Norse runic symbols https://i.imgur.com/iqpnQjR.png

And it is a Swedish innovation engineered by Ericsson in the 90s. Very interesting how Sweden was one of the biggest countries exporting new network communication back then

Btw the name is Harald ''Blåtand'' in swedish so the initials work both in english and the original language which is nice
