Google’s plan to block tracking tool draws US antitrust scrutiny: Report

(Reuters) – Google’s plan to block a popular web tracking tool called “cookies” is a source of concern for U.S. Justice Department investigators who have been asking advertising industry executives whether the move by the search giant will hobble its smaller rivals, people familiar with the situation said.

Alphabet Inc’s Google a year ago announced it would ban some cookies in its Chrome browser to increase user privacy. Over the last two months, Google released more details, leading online ads rivals to complain about losing the data-gathering tool.

The questions from Justice Department investigators have touched on how Chrome policies, including those related to cookies, affect the ad and news industries, four people said.
