Mobile Marketing  is meant to describe marketing on or with a mobile device, such as a mobile phone.  Marketing on a mobile phone has become increasingly popular ever since the rise of SMS (Short Message Service) in the early 2000s in Europe and some parts of Asia when businesses started to collect mobile phone numbers and send off wanted (or unwanted) content.  SMS services typically run off a short code, but sending text messages to an email address is another methodology.   One key criterion for provisioning is that the consumer opts in to the service. The mobile operators demand a double opt in from the consumer and the ability for the consumer to opt out of the service at any time by sending the word STOP via SMS.

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 (wikipedia.com).
