Sources: EU antitrust regulators plan to open a formal investigation into Google's digital advertising business before the end of the year
EU antitrust regulators are set to open another front against Alphabet (GOOGL.O) unit Google by launching a formal investigation …
Context & Ripple Effects
This is the opening move in what became one of Brussels' longest-running cases against Google: sources say regulators planned to open a formal probe into the ad business before year-end, days before the Commission confirmed an investigation into whether Google favors its own display ad tech over rivals. The arc that followed shows why the timing matters — slow settlement talks stretched into 2022, with sources reporting the EU could file charges as frustration mounted over stalled settlement negotiations.
The case ultimately matured into a formal statement of objections on the ad tech stack and, by 2025, a modest fine triggered by a European Publishers Council complaint — a muted outcome relative to the four-year runway. This article is the moment the case was born, which makes it the reference point for judging whether that outcome reflects regulatory restraint or a strategy that ran out of leverage.
First-order effects
- Google's ad tech unit — the self-preferencing display tools at issue — comes under formal Commission investigation, adding legal overhead and disclosure obligations while the company's core search and Android cases were already consuming regulator attention.
- Publishers and rival ad-tech vendors who complained about Google favoring its own exchange gain a procedural vehicle: the European Publishers Council's later complaint rode the groundwork this investigation established.
Second-order effects
- Google's settlement posture hardens: with a formal case open, the company negotiates remedies rather than walking away from talks, which is precisely the dynamic sources later described when charging decisions slipped past the original timeline.
- Rival ad-tech intermediaries get a competitive opening to pitch publishers on non-Google stacks while the incumbent's practices sit under formal review.
Third-order effects
- If the pattern holds — years of investigation ending in a comparatively small fine — EU enforcement against ad-tech self-preferencing looks more like a tax on delay than a structural remedy, pushing real pressure onto instruments like the DMA, where regulators separately moved to charge Google over search-results changes.
- The publishers-versus-platform complaint model, validated by this case's origin, becomes the standard route for media companies seeking ad-tech intervention in Europe.
The trend: EU competition enforcement is shifting from multi-year bespoke antitrust investigations toward faster, rules-based DMA actions, with the Google ad tech case marking the high-water mark of the old model.
