Mobile Bluetooth Marketing
The rise of Bluetooth started around 2003 and a few companies in Europe have started establishing successful businesses. Most of these businesses offer "Hotspot-Systems" which consist of some kind of content-management system with a Bluetooth distribution function. This technology has the advantages that it is permission-based, has higher transfer speeds and is also a radio-based technology and can therefore not be billed (i.e. is free of charge). The likely earliest device built for mobile marketing via Bluetooth was the context tag of the AmbieSense project (2001-2004). More recently Tata Motors conducted one of the biggest Bluetooth Marketing campaigns in India for its brand the Sumo Grande.
