The most publicized effort under Leibowitz's belt is the FTC's antitrust investigation into Google's business practices. The 20-month probe focused mostly on the way Google displayed search results, which critics said favored the company's own services over those of its competitors.
Under the FTC's settlement, a handful of companies can now choose to stop showing their results inside Google products like Google+ Local, Google Shopping, and Hotels. The search giant also agreed to voluntarily change the way it uses other Web sites' data. However, some regulatorsthat the settlement agreement was akin to a slap on the wrist and that despite the probe, Google is continuing to operate as normal with its search results looking more or less the same.
