State attorneys general investigating Google are ordering it to turn over a wide range of information about its advertising business, according to an investigative demand that takes direct aim at the biggest source of the company’s revenue.

According to the document, the states want information about Google’s past acquisitions of advertising technology companies, including DoubleClick and AdMob; its top advertisers and publishers; data collection practices; pricing models; and the functions of the ad auction market that delivers ads across the internet.
