In a year when behavioral advertising was already expected to be at the top of the hot button privacy issues list, on January 13, 2008, the Center for Digital Democracy (“CDT”) and U.S. Public Interest Research Group (“US PIRG”) filed a document with the Federal Trade Commission (“FTC”) urging the FTC to investigate online mobile marketing practices, to take new actions to stop mobile marketing activities that “abuse consumer rights,” and to recommend new federal legislation and enhanced enforcement power for the FTC in this area. The document expands on the groups’ concerns about online behavioral advertising generally – the delivery of ads tailored to consumers’ interests based on browsing habits and/or consumer demographics – to the mobile space. In doing so the groups cite the potential for even greater consumer harm because of the additional possibility of location-based targeting linked to a cell phone or other mobile device that is typically tied to a single consumer who uses it for multiple applications, including voice, video and data.
