The antitrust hearing scheduled for today for the CEOs of Apple, Amazon, Facebook, and Google has been postponed to Wednesday following the death of Rep. John Lewis.

Lewis died on 17 July and his body is to lie in state at the US Capitol this week. The hearing has been moved to Wednesday from Monday to allow members of Congress to pay their respects to Lewis, the longstanding politician and civil rights leader.

The hearing, which will in all likelihood be held virtually, is for the House Judiciary Committee to question Tim Cook, Jeff Bezos, Mark Zuckerberg, and Sundar Pichai, the CEOs of four of the most monopolistic American tech companies, about their dominance. In particular questions are expected to address how Google owns over 90% of the search market, Apple’s App Store policies, Amazon’s ethics around third party sellers, and Facebook’s acquisitions of Instagram and WhatsApp.

With these four companies having so much influence over the course of technology in the States and the world, the hope is a solution may be found that makes the industry more competitive. With more competition usually comes better products for people, and a freer market.

House Judiciary Committee Chairman Jerrold Nadler and Antitrust Subcommittee Chairman David Cicilline prefaced the hearing by declaring:

“Since last June, the Subcommittee has been investigating the dominance of a small number of digital platforms and the adequacy of existing antitrust laws and enforcements. Given the central role these corporations play in the lives of the American people, it is critical that their CEOs are forthcoming. As we have said from the start, their testimony is essential for us to complete this investigation.”

The hearing is expected to stream free on the House Judiciary’s YouTube channel.
