About Bluetooth

Bluetooth technology was invented in 1994 by engineers at Ericsson, a Swedish company. In 1998, a group of companies agreed to work together using Bluetooth technology as a way to connect their products. These companies formed the Bluetooth Special Interest Group (SIG), an organization devoted to maintaining the technology. This means that no single company "owns" Bluetooth technology, but that many members of the Bluetooth SIG work together to develop Bluetooth technology.

Founding members were Ericsson, Nokia, Intel, IBM and Toshiba.

Almost all of the biggest companies in the telecommunications business have joined the Bluetooth SIG and the number of the participating companies is now over 1500.
