The House Commerce Committee’s hearing on the FTC’s proposed "Do Not Track" registry is scheduled for tomorrow, December 2nd. Details, along with a witness list, are on the House Commerce Committee’s website.
According to the announcement, the hearing "will examine the feasibility of establishing a mechanism that provides Internet users a simple and universal method to opt-out from having their online activity tracked by data-gathering firms." It not clear whether tomorrow’s hearing will address hybrid online/offline tracking. Apple responded in July to a Congressional letter regarding its GPS-based tracking practices, but it is not on the invited witness list.
The concept of a universal “Do Not Track” list traces back to at least 2007, when an alliance of privacy groups proposed a list to the FTC, modeled after the FTC’s successful “Do Not Call” list (See Wall Street Journal Article).
