A US House of Representatives panel has widened its anti-trust probe into giant technology companies, with demands for internal e-mails, detailed financial information and other company records.
The panel sought the information from top executives of Amazon, Facebook, Apple and Google.
The lawmakers want a decade of internal e-mails relating to acquisitions from Apple’s Tim Cook, Amazon CEO Jeff Bezos, Facebook’s Mark Zuckerberg and Alphabet CEO Larry Page, among others.
The lawmakers say there is growing evidence that a handful of corporations have captured an outsized share of online commerce and communications.
They say the e-mails have been key in helping determine whether anti-competitive behaviour is occurring.
They could also trigger an investigation by US antitrust enforcement agencies and determine whether antitrust laws need improvement to better promote competition in digital markets.
