Bluetooth History
1994: Bluetooth is defined by Ericcson.
1998: Ericcson, IBM, Intel, Nokia, and Toshiba formed
Bluetooth SIG (Special Interest Group)
1999: The first Bluetooth consumer product, a hands-free
mobile.
2003: Each week more than 1 million Bluetooth-enabled
products were sold
2011: more then 3 billon Bluetooth-enabled products
and 14,000 BT SIG member.
2011: BT Version 4.0, Bluetooth low energy (BLE)
