The Consumer Financial Protection Bureau announced Thursday it had issued orders for information to Amazon, Apple, Facebook, Google, PayPal and Square on their use of consumer data.
Questions will examine the use of data harvesting and monetization, and other consumer protection issues.
The CFPB's new director, Rohit Chopra, previously served as a Federal Trade Commissioner, where he was highly critical of Big Tech companies and their data practices. The CFPB said its move built on the FTC's "work to shed light on the business practices of the largest technology companies in the world."
The Wall Street Journal previously reported the orders.
