'Do Not Track' Web Browser Option Gains Steam

Government regulators in the U.S. and Europe are putting pressure on the online advertising industry to adopt a new Web browser option called "do not track."

The option is designed to let people request more privacy from the websites they visit. But there's no consensus yet on how much privacy users should expect. An Internet industry task force convenes April 10 in Washington to try to hash that out. Some browsers, like Internet Explorer, Safari and Firefox, already come with a "do not track" button. Other browsers are expected to add the feature soon.
