Chief executives from four of the world’s most powerful companies will defend the vast empires they’ve built in testimony before Congress on Wednesday.

In a hearing held by the House’s Antitrust Subcommittee, Jeff Bezos, Tim Cook, Sundar Pichai and Mark Zuckerberg will all face questions about how their business practices propelled them into the market-dominant giants they are today. Amazon, Apple, Google and Facebook make up four of top six most valuable public companies in existence and are widely regarded as reshaping the consumer world, both within the tech industry and beyond.
