The article reports on the move of the U.S. House Energy and Commerce Committee to publish letters, which raised questions to Internet and telecommunication providers about their data gathering and targeting practices. It cites that the committee was concerned over the use of deep-packet inspection (DPI) by Web firms, which was found to have driven increased scrutiny to issues around online advertisements. Moreover, the committee has planned to pass a consumer privacy bill of rights in 2009.
