Knock, Knock: Dingell-gram for Mr Embarq Concerning Mr NebuAd

House Commerce Committee Chairman John Dingell (D-MI) and Ranking Member Joe Barton (R-TX) have written Embarq (phone and Internet bundled with satellite TV) raising questions about a test to tailor advertising to Web-browsing histories using NebuAd. Pointing out that they have concerns about online privacy in general and in particular are concerned that Embarq may not have notified customers that they were being profiled during a test with NebuAd earlier this year, the legislators want some information from the company, including where the test was conducted; how many customers were involved; how customers were notified and, if not, why not; why it was an "opt-out" rather than an "opt-in" model; and more.
