The long-awaited antitrust trial between Meta and the Federal Trade Commission kicked off on April 14th. Over about two months, DC District Court Chief Judge James Boasberg is hearing arguments about whether then-Facebook illegally monopolized the market for “personal social networking services” through its acquisitions of Instagram and WhatsApp.

The trial between the US Federal Trade Commission and Meta began this week—and the future of the company is at stake. The FTC wants Meta to sell off two prized assets, Instagram and WhatsApp, arguing that it acquired them illegally to suppress competition.

Meta CEO Mark Zuckerberg took the stand on Monday in a historic antitrust trial that could force the tech giant to break off Instagram and WhatsApp, startups it bought more than a decade ago that have since grown into social media powerhouses.
