Where was bluetooth found for first time?

Bluetooth technology was first developed in 1994 by a team at Ericsson, a Swedish telecommunications company. The name "Bluetooth" is derived from Harald "Bluetooth" Gormsson, a 10th-century king of Denmark known for uniting the tribes of Denmark and Norway, symbolizing the unification of various devices through wireless communication. The first practical applications of Bluetooth appeared in mobile phones and other personal devices in the late 1990s.
