The Bluetooth Special Interest Group (SIG) is a privately held, not-for-profit trade association. The Special Interest Group was founded in September 1998. The Bluetooth SIG itself does not make, manufacture, or sell Bluetooth enabled products. The main tasks for the Bluetooth SIG are to publish Bluetooth specifications, administer the qualification program, protect the Bluetooth trademarks and evangelize Bluetooth wireless technology.

The SIG has more than 12,000 member companies that are leaders in the telecommunications, computing, automotive, music, apparel, industrial automation, and network industries. SIG members drive development of Bluetooth wireless technology, and implement and market the technology in their products.
