Ars Technica has a nice recap of the case so far:
The Department of Justice called its last witness this week, resting its case in a blockbuster antitrust trial probing Google’s alleged monopoly over search. Over the next five weeks, Google will do everything in its power to defend against those allegations—or else risk a potential breakup of its lucrative, industry-dominating search business—including likely calling Google CEO Sundar Pichai and other top executives as witnesses.
Since the trial began on September 12, Judge Amit Mehta has heard testimony from 29 witnesses, Bloomberg reported, including leading economists and senior executives from Google, Apple, Microsoft, Samsung, and other tech companies either partnering with or rivaling Google over the years.
Much of this testimony was closed to protect tech companies’ trade secrets, but news outlets have since filed a motion hoping to unseal testimony and access more trial documents sooner, hoping to share more details with the public about the case the DOJ made.
That this case was brought at all is a major milestone. For many years, the U.S. federal government let Google do whatever it wanted, leaving the European Union to provide regulatory oversight. There was little oversight or accountability from Google’s home country. Now, Google is finally on trial for its illegal conduct and harmful business practices. The decision won’t be made by a jury, but the government has brought lots of compelling evidence to the table that will hopefully result in a decision from Judge Mehta that Google violated the country’s antitrust laws.
