“Do Not Track” (DNT) is gaining momentum. In 2007, CDT and a coalition of other public interest groups called on the Federal Trade Commission (FTC) to create a Do Not Track system that consumers could use to avoid being tracked as they browsed the Web. For three years, the idea went nowhere. Then, last July, FTC Chairman Jon Leibowitz expressed support for DNT in Congressional testimony. In December, the FTC staff featured DNT in its draft privacy report and a House subcommittee held a hearing on the topic.
