Leaders of Big Tech Companies Asked to Testify on Market Power

Leaders of big tech companies will be asked to testify as part of an investigation into whether the companies misuse their massive market power, the head of the U.S. House Judiciary subcommittee leading the probe said. The comments came a day after sources said the U.S. executive branch is gearing up for a similar probe of Amazon.com Inc, Apple Inc, Facebook Inc and Alphabet Inc’s Google, setting up what could be an unprecedented, wide-ranging investigation of some of the world’s largest companies.
