The nomenclature and symbol associated with Bluetooth, a ubiquitous wireless technology facilitating device connectivity, have roots deeply embedded in the history of medieval Scandinavia. The name "Bluetooth" harks back to King Harald Gormsson, a 10th-century Danish monarch renowned for unifying Denmark, introducing Christianity to the region, and expanding his rule into Norway. The epithet "Bluetooth" stems from the king's discolored, possibly blue, dead tooth.

In the late 20th century, during collaborative efforts by Ericsson, Intel, and Nokia to devise a standardized wireless communication protocol, the quest for a name led to an intriguing historical connection. Jim Kardach, representing Intel, suggested "Bluetooth" with the metaphorical intention of mirroring King Harald's unifying achievements. The name aimed to symbolize the technology's role in uniting various products across diverse industries.

Despite historical nuances regarding the extent of King Harald's unification efforts in Scandinavia, the name "Bluetooth" gained international prominence. The Bluetooth symbol, representative of this wireless technology, further integrates historical elements. Crafted in runes, the ancient Scandinavian alphabet, the symbol combines the runes for "H" and "B," signifying Harald Bluetooth's initials. Thus, beneath the surface simplicity of the name and symbol lies a rich historical narrative, adding layers of significance to the technology's identity.
