A judge ruled Google broke antitrust law, then let it keep its entire ad-tech business

A federal court ruled that Google had violated antitrust laws related to its ad-tech business on Wednesday. Despite this finding, the judge upheld Google's entire ad-tech division, which was a significant win for the company after the Justice Department had demanded it be broken up. Judge Leonie M. Brinkema ruled that divestiture was neither feasible nor necessary, even after finding Google's actions in the ad-tech market to be anti-competitive.

Instead, the court mandated changes to the way Google's advertising technologies function. These changes include making Google's products work with competing technologies, sharing more auction data with publishers, and appointing an internal monitor to ensure compliance.

Google's ad-tech products are integral to the process of selling ad space on third-party websites, such as news, recipe, and entertainment sites. The Justice Department contended that Google used its dominant position in the ad-tech market to secure a larger share of ad sales than in a more competitive environment. Judge Brinkema concurred with the Justice Department's assessment that Google had unlawfully maintained its monopoly in certain aspects of the ad-tech industry.

The new ruling aims to provide publishers with more information about the auction process and facilitate the integration of competing ad platforms with Google's technology. The remedies largely followed suggestions from both parties involved.

Google argued that it could not separate its ad exchange business from the rest of its ad-tech operations due to their tight integration. Instead, the company proposed measures like improved pricing transparency and oversight by a trustee. Google's global head of regulatory affairs, Lee-Anne Mulholland, expressed satisfaction with the court's decision to reject the Department's proposal to separate Google's ad exchange from the rest of its ad-tech operations.

The Justice Department stated that they were reviewing the decision, with Associate Attorney General Stanley E. Woodward Jr. calling it a "significant victory" for the department's efforts to promote competition.

Some industry players, including publishers and ad-tech executives, felt the ruling should have been more extensive. Jason Kint, CEO of Digital Content Next, criticized the court for not ordering a breakup, even though Google had monopolized and tied together various elements of the digital advertising market. Nikhil Lai, a principal analyst at Forrester, noted that courts generally avoid breaking up large companies and often opt for measures that could give competitors a better chance to compete.

Lai suggested that innovation might be more influential than litigation in the long run. The ruling comes as Alphabet, Google's parent company, continues to invest heavily in artificial intelligence, particularly in search and other major products. Judge Brinkema acknowledged that AI has yet to significantly impact ad technology the way it has affected search.

However, she warned that significant industry disruptions caused by AI could potentially overshadow the ongoing legal proceedings. Google's ad-tech business generated $30 billion in revenue last year, accounting for approximately 8% of Alphabet's total revenue. The unit's revenue has declined in 16 consecutive quarters, and analysts estimate it contributes less than 1% to Alphabet's profit.

This decision marks Google's second major antitrust victory in court. Federal judges have found Google to be a monopolist in both search and advertising technology, but no case has resulted in an order to dismantle the company so far.
