 
     The name “Bluetooth”  and its logo are trademarked by the privately held trade association  named the Bluetooth Special Interest Group (SIG).  
     Founded in  September 1998, the Bluetooth SIG is a unification of leaders in the  telecommunications, computing, network, industrial automation, and Automotive  industries. Today, the Bluetooth SIG is responsible for encouraging and  supporting research and development in Bluetooth technology.
The  Bluetooth SIG includes promoter member companies Microsoft, Ericsson,  IBM, Intel, Agere, Motorola, Nokia, and Toshiba, plus thousands of  Associate and Adopter member companies (BlueTomorrow.com's parent  company, SP Commerce LLC, is a licensed and certified Adopter member of  the Bluetooth SIG).
Why is It Called Bluetooth?
     The developers of this wireless  technology first used the name "Bluetooth" as a code name, but as time  past, the name stuck.
     The word "Bluetooth" is taken from the 10th  century Danish King Harald Bluetooth. King Bluetooth had been  influential in uniting Scandinavian Europe during an era when the region  was torn apart by wars and feuding clans. 
    The founders of the  Bluetooth SIG felt the name was fitting because: 
1)  Bluetooth technology was first developed in Scandinavia, and 
2)  Bluetooth technology is able to unite differing industries such as the  cell phone, computing, and    automotive markets. Bluetooth wireless  technology simplifies and combines multiple forms of wireless  communication into a single, secure, low-power, low-cost, globally  available radio frequency.
Bluetooth Technology Over the Years

1999 -  Bluetooth 1.0 Specification is introduced.
2003 -  The Bluetooth SIG overhauls the Bluetooth Core Specification with the  announcement of Version 2.1.
2004 - Bluetooth  Version 2.0 + EDR (Enhanced Data Rate) is      introduced.
2005 -  Devices using Version 2.0 + EDR begin to hit the market in  late 2005.
2007 - Bluetooth Core Specification  Version 2.1 + EDR is adopted by the Bluetooth SIG.
2009 - Bluetooth  Core Specification Version 3.0 + HS (High Speed) is adopted by the  Bluetooth SIG.
