An anonymous reader quotes a report from The Guardian: After deflecting the US Department of Justice's attack on its illegal monopoly in online search, Google is facing another attempt to dismantle its internet empire in a trial focused on abusive tactics in digital advertising. The trial that opened Monday in an Alexandria, Virginia, federal court revolves around the harmful conduct that resulted in US district Judge Leonie Brinkema declaring parts of Google's digital advertising technology to be an illegal monopoly in April. The judge found that Google has been engaging in behavior that stifles competition to the detriment of online publishers that depend on the system for revenue.
Google and the justice department will spend the next two weeks in court presenting evidence in a "remedy" trial that will culminate in Brinkema issuing a ruling on how to restore fair market conditions. If the justice department gets its way, Brinkema will order Google to sell parts of its ad technology -- a proposal that the company's lawyers warned would "invite disruption and damage" to consumers and the internet's ecosystem. The justice department contends a breakup would be the most effective and quickest way to undercut a monopoly that has been stifling competition and innovation for years. [...]
The case, filed in 2023 under Joe Biden's administration, threatens the complex network that Google has spent the past 17 years building to power its dominant digital advertising business. Digital advertising sales account for most of the $305 billion in revenue that Google's services division generates for its corporate parent Alphabet. The company's sprawling network of display ads provide the lifeblood that keeps thousands of websites alive. Google believes it has already made enough changes to its "ad manager" system, including providing more options and pricing options, to resolve the problems Brinkema flagged in her monopoly ruling.
