Reporting from Washington — Yahoo Inc. will offer a "do not track" feature on all its websites by early summer that will allow consumers to opt out of targeted advertisements based on data collected about their online movements, the company said Thursday.
The new feature has been in development since last year and will "provide a simple step for consumers to express their ad-targeting preferences to Yahoo," the company said.
Most major Web browsers, including Mozilla's Firefox, Microsoft Corp.'s Internet Explorer and Apple Inc.'s Safari have added a "do not track" button in the last year or so as privacy advocates and Washington policymakers have pushed to give consumers more power over their online data.
Google Inc.said in February that it would add the feature to its Chrome browser by the end of the year.
Yahoo, Google and other major online advertising companies have been working to provide a standardized Do Not Track feature for consumers.
