The Interactive Advertising Bureau on Thursday called on the Federal Trade Commission withdraw recently issued enforcement guidance regarding the opinions and commentary of bloggers online marketers and others, saying the rules unfairly and unconstitutionally impose penalties on online media for practices in which offline media have engaged for decades. In an open letter to FTC Chairman Jon Leibowitz, IAB President Randall Rothenberg called the agency's distinction between offline media and online media, "constitutionally dubious."
