European commission files third antitrust charge against Google

Charge against firm's advertising arm follows reinforced filing against shopping service and probe into alleged abuse of Android

The European commission has filed a third antitrust charge against Google, this time against its AdSense advertising business.

The EU regulator accuses Alphabet's Google of abusing its dominance in search to benefit its own advertising business, which has historically been the company's main revenue stream. The EC also reinforced its existing charge against Google's shopping service, which the regulator says receives preferential treatment in search results.
