EU to Probe High Tech Firms' Market Power

The European Union will announce a wide-ranging probe into how big technology companies such as Google, Amazon and Facebook use their market power as it considers whether to regulate them more tightly. The inquiry, which by its nature will inevitably focus heavily on U.S. firms, follows calls from France and Germany for regulation of so-called "essential digital platforms", encompassing everything from e-commerce sites such as eBay to social media companies.
