Mobile marketing is marketing on or with a mobile device, such as a cell phone. Mobile marketing can also be defined as “the use of the mobile medium as a means of marketing communication”, the “distribution of any kind of promotional or advertising messages to customer through wireless networks”. More specific definition is the following: “using interactive wireless media to provide customers with time and location sensitive, personalized information that promotes goods, services and ideas, thereby generating value for all stakeholders".
Mobile marketing is commonly known as wireless marketing, although viewing advertising on a computer connected to a home local area network is not considered to be mobile marketing.
Marketing through cellphones' SMS (Short Message Service) became increasingly popular 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. On average, SMS messages are read within four minutes, making them highly convertible.
Over the past few years SMS marketing has become a legitimate advertising channel in some parts of the world. This is because unlike email over the public internet, the carriers who police their own networks have set guidelines and best practices for the mobile media industry (including mobile advertising). The IAB (Interactive Advertising Bureau) and the Mobile Marketing Association, as well, have established guidelines and are evangelizing the use of the mobile channel for marketers. While this has been fruitful in developed regions such as North America, Western Europe and some other countries, mobile SPAM messages (SMS sent to mobile subscribers without a legitimate and explicit opt-in by the subscriber) remain an issue in many other parts or the world, partly due to the carriers selling their member databases to third parties. In India, however, government's efforts of creating National Do Not Call Registry have helped cellphone users to stop SMS advertisements by sending a simple SMS or calling 1909.
Mobile marketing via SMS has expanded rapidly in Europe and Asia as a new channel to reach the consumer. SMS initially received negative media coverage in many parts of Europe for being a new form of spam as some advertisers purchased lists and sent unsolicited content to consumer's phones; however, as guidelines are put in place by the mobile operators, SMS has become the most popular branch of the Mobile Marketing industry with several 100 million advertising SMS sent out every month in Europe alone.
