The news is out from this year's Mobile Marketing Forum: blue chip brand marketers including Procter & Gamble and MasterCard, among others, plan to dedicate a portion of their media budget to mobile marketing programs as opposed to discretionary ad hoc tests as has been the case for the better part of the last 12 to 18 months. Of course, there are major pros and cons of mobile marketing. But first, the service providers need to make sure they are ready to cozy up to marketers with clear and concise offerings and relatively modest guarantees. One of the negatives that is sure to come out this story is the whole privacy issue as marketers test geo-targeted placements through various service providers, for example, Joe Blow who is Sprint/Nextel subscriber is walking down main street U.S.A. and walks past a Best Buy, using location based technology, Sprint/Nextel sends Mr. Blow a $50 coupon if heads into the Best Buy within the hour. The privacy advocates will go nuts on that scenario. There are tons of other channel marketing opportunities within the mobile space, but I would have to think location-based would be the most appealing to marketers, at least for now.
