Japan's mobile advertising market was launched in 2000, the year after NTT docomo introduced its new Internet-connected i-mode mobile phone service.

Prior to this point, mobile phones had been used mainly for voice calls alone. However, with the launch of i-mode and other mobile Internet services, consumers gained the ability to send and receive email, browse the Internet, and download digital content to their phones.  These new features allowed portable mobile phones to become established as both a new media and an innovative tool. In becoming a major media channel, mobile phones became a key means for consumers to encounter information.  In time, mobile has also emerged as an extremely valuable advertising platform as well. 

 In addition, in becoming a key tool for consumers, mobile has allowed email and mobile Internet sites to emerge as a platform for interactive communication.  This in turn has allowed companies to adopt mobile phones for interactive communication with their customers. This new technique of marketing is what has now been termed mobile marketing.
