Together with its sister site MobileBeyond, IM-Mobile is dedicated to mobile marketing and advertising, as well as emerging wireless technologies. On October 16, 2009, MobileBeyond/IM-Mobile spotlighted 15miles president Gregg Stewart in a podcast interview about local search on mobile platforms. In the interview, Stewart called upon the recent release of TMPDM/15miles’ annual local search study to explain the rapid usage growth of iPhones and other Web-based smartphones, which has caused many marketers to understand and tap into the power of mobile marketing as a personal engagement tool. Said Stewart, “…Since the release of the iPhone and other smartphones, brands are beginning to understand the unique, personal engagement characteristics of mobile phones and are testing multimedia marketing campaigns incorporating mobile.”
