Ian Lamont writes "An advertising company that runs a 'targeting marketplace' and partner AT&T are playing down the telecommunications giant's use of its services after AT&T's chief privacy officer told a House subcommittee yesterday that the company does not engage in behavioral advertising. The AT&T executive testified (PDF) to the House of Representatives Subcommittee on Communications, Technology and the Internet that AT&T would not use behavioral advertising methods without informed customer consent. However, AudienceScience, a company that records 'billions of behavioral events daily' has apparently worked for AT&T since 2005. After the hearing, AudienceScience removed a client testimonial relating to AT&T from its website, so 'all the appropriate parties [have] consistent messaging,' its CEO said. An AT&T spokesman also said that the testimony was talking about AT&T's role as an ISP, not an advertiser."
