Google is currently embroiled in a fresh challenge from U.S. antitrust regulators. The U.S. Department of Justice has put forth a demand for Google to divest itself of its key online advertising business, AdX. Moreover, it insists that Google make the source code for its ad - bidding winning mechanism open - source.

Previously, the presiding judge, Leonie Brinkema, handed down a ruling stating that Google had indulged in illegal monopolistic practices within the online advertising technology sector. The specific remedies to address this situation will be determined after the conclusion of this week's trial.

This particular case is a component of the U.S. government's crackdown on major tech firms. The government's allegations are rooted in Google's unlawful practice of bundling publisher ad servers with the AdX platform.

Confronted with the looming threat of a breakup, Google has put forward alternative policy modifications. It contends that the Department of Justice's proposal is technically unworkable.

Last year, during its negotiations with the EU, Google proposed the sale of AdX. Its related internal research might be presented as evidence during this week's trial. Additionally, several industry executives are anticipated to take the stand and testify.
