Lawmakers and activists have raised concerns about the growing dominance of online giants such as Google, Facebook and Amazon in key segments of the digital economy (Alastair Pike)

San Francisco (AFP) – Top prosecutors from a group of US states are readying a joint investigation into whether major technology firms have violated antitrust law, the Wall Street Journal reported Monday.

The alliance of state attorneys general could formally announce next month that they are delving into whether leading internet firms and technology platforms have used their clout to thwart competition, the Journal reported, citing unnamed people familiar with the matter.

The US Department of Justice last month announced it is reviewing “whether and how market-leading online platforms have achieved market power and are engaging in practices that have reduced competition, stifled innovation, or otherwise harmed consumers.”

Lawmakers and activists have raised concerns about the growing dominance of online giants such as Google, Facebook and Amazon in key segments of the digital economy.

Once seen as the darlings of Washington, Silicon Valley firms have become targets for politicians of all stripes. US regulators recently imposed a record $5 billion fine on Facebook for lapses in privacy and data protection, including the leaking of private data for political consultancy Cambridge Analytica.

Tech firms and their backers deny monopolistic conduct and argue the fast-evolving digital economy has robust competition and has led to lower prices and more choice for consumers.
