Google begins its battle for the ‘unofficial currency of the internet’

Google faces a potential breakup of its digital advertising business as the DOJ argues its AdX exchange and DFP ad server have created an illegal monopoly over "the unofficial currency of the internet." The government wants Google to sell AdX and open-source its auction logic to restore competition in online advertising markets. Publishers testify they're locked into Google's tools despite quality issues, while Google counters that behavioral changes would be less disruptive than the "radical" structural remedies proposed.
