As first revealed by a tweet from famed technology journalist Kara Swisher, the CEOs of Facebook, Apple, Amazon, and Google, the big four tech giants, have agreed to a summons to an antitrust hearing that’s scheduled to hold late in this month. Swisher cites her source as U.S. Congressman David Cicilline, himself a big critic of the four tech giants. Tech giants, in particular, aren’t new to congressional hearings, but the CEOs of Apple, Amazon, Facebook, and Google testifying at a single hearing isn’t common. These companies are notably under antitrust scrutiny from regulatory authorities. Their respective chief executives, by names Tim Cook, Jeff Bezos, Mark Zuckerberg, and Sundar Pichai, are apparently set for a testimony to the House Judiciary antitrust subcommittee soon.

SCOOP: You can officially call it Techopalooza. Rep. David Cicilline has told me in an interview today the four CEOs of the most powerful tech companies in the world – Apple, Facebook, Google and Amazon – have agreed to appear at a late July hearing on antitrust. Column coming!
