Several Internet and broadband companies have acknowledged using targeted-advertising technology without explicitly informing customers, according to letters released yesterday by the House Energy and Commerce Committee.

The revelations came in response to a bipartisan inquiry of how more than 30 Internet companies might have gathered data to target customers. Some privacy advocates and lawmakers said the disclosures help build a case for an overarching online-privacy law.
"Increasingly, there are no limits technologically as to what a company can do in terms of collecting information . . . and then selling it as a commodity to other providers," said committee member Edward J. Markey (D-Mass.), who created the Privacy Caucus 12 years ago. "Our responsibility is to make sure that we create a law that, regardless of the technology, includes a set of legal guarantees that consumers have with respect to their information."
Markey said he and his colleagues plan to introduce legislation next year, a sort of online-privacy Bill of Rights, that would require that consumers must opt in to the tracking of their online behavior and the collection and sharing of their personal data.
