Public relations agency Reverb communications, hired by iPhone game developers to promote their App Store offerings, has reached a settlement with the FTC over accusations that company employees posted positive reviews for the games the company was hired to promote. The FTC levied charges against Reverb for violating rules that require the sellers of products and those posting information about the products online to disclose any connection they might have. The FTC first began looking into practices of “stealth marketing,” which seeks to build product buzz via blogs, social media, and word of mouth by quietly paying “ordinary” people to promote the product, in late 2006 .
