Mobile technologies have dramatically changed the world’s ability to communicate. The number of mobile phones used worldwide has exceeded 4.6 billion with continued growth expected in the future. In fact, in the United States alone, the numbers of mobile phone users comprise over 80% of the population. Mobile phones and tablets (mobile devices) are not simply voice communication devices. They have become a medium to create voice, music, text, video, and image communications. Importantly, these various types of communication can be created and shared on demand by the mobile user. In addition to communication methods, mobile devices are also a tool used to access the Internet, view television and movies, interact with GPS (Global Positioning System), and read and respond to barcode and augmented reality messages. Each of these methods utilized by the mobile phone user becomes a tool that can be used in mobile marketing to expand beyond traditional marketing methods. Mobile devices are considered to be “the most personal piece of technology that most of us will ever own” (Krum, 2010, p. 7). We usually take them with us wherever we go and are usually reachable through them. However, mobile devices also provide the ability to access the most personal information about us. Mobile devices know who we communicate with and how often. They know our schedule – both business and personal. They often know all of our email addresses and frequently accessed web sites. They know what videos, music, television shows, and movies we like. They know about us through pictures and text messages sent and received. They know where we go, how often, and how long we stay through location tracking technology. This collection of accessible personal information allows mobile marketing to target individuals at the time and place where their message will be most effective. Mobile technologies over the past 20 years have dramatically changed the way people communicate, collaborate, search for, receive, and share information. These dramatic changes have had striking impact on the world of marketing to the extent that mobile marketing has become the predominant form of customer engagement.
