WASHINGTON — More than half of state attorneys general are planning to open an antitrust investigation of Alphabet Inc.'s Google next week, according to two people familiar with the matter.

Multiple states are planning to announce the coordinated probe on Sept. 9, said three people, who asked not to be identified discussing sensitive deliberations. The plans could change.

U.S. antitrust enforcers have already taken preliminary steps toward a probe of the search giant, which is also a major player in online ads and mobile operating systems. It has faced antitrust investigations in Europe as well.

It was not immediately clear what the probe would focus on or which states would participate.

A group of state attorneys general said in June at an enforcement workshop hosted by the Federal Trade Commission that they are examining a wide range of practices, including data collection, digital advertising and innovation, among large tech companies.

SAN FRANCISCO — Facebook says it is ending its practice of using face recognition software to identify users’ friends in uploaded photos and automatically suggesting they “tag” them.Instead, it is replacing the feature, called “tag suggestions,” with its broader face recognition setting, which identifies people’s faces in photos for various uses, not just tagging. Beginning Tuesday, people who are new to Facebook, or previously had the tag suggestions setting turned on, will instead get the face recognition setting, which they can turn on or off.People who had the tag suggestions setting turned off will see a notice about face recognition and a button to turn it on or keep it off.Facebook was sued in Illinois over the tag suggestion feature and a federal appeals court has ruled the lawsuit can proceed.
