Many people have told us that they think opting out is confusing. We agree. Opting out can range from the not-too-difficult (the FTC’s Do Not Call list is a fairly simple opt out) to the challenging (the National Advertising Initiative opt out can be tricky). Our hope is that this list will clarify which opt out does what, and how to go about opting out.
Current online privacy debates focus on respecting the privacy interests of Internet users while accommodating business needs. Formal and informal proposals for improving consumer privacy offer different ideas for privacy regulation and privacy self-regulation, sometimes called codes of conduct.  Some in the Internet industry continue to advance or support ideas for privacy self- regulation. Many of these same players proposed and implemented privacy self-regulatory schemes that started in the late 1990s.
This section offers a historical review of privacy self-regulation that occurred in the years just before and just after 2000. For a variety of reasons, it is not necessarily fully comprehensive. Some self-regulatory efforts may have disappeared without a trace. Activities within existing trade associations are difficult or impossible to assess from evidence available to those outside the associations. However, this discussion captures the leading organizations of the time. 
This section reviews several other privacy self-regulatory activities that share some characteristics with the industry self-regulatory programs discussed above, but these activities differ in various ways. The most noticeable differences are the role of the government in the programs. The Department of Commerce is involved in the Safe Harbor Framework, and the Federal Trade Commission is involved in the Children’s Online Privacy Protection Act.
The self-regulatory efforts in this category include projects that have many components, including input from government, industry, academia, and civil society.
