Like Europe before it, the U.S. government looks ready to try reining in its technology giants. But doing so may be more difficult than it seems.
 Â
On Tuesday, the U.S. Department of Justice opened a sweeping antitrust investigation of major technology companies and whether their online platforms have hurt competition, suppressed innovation or otherwise harmed consumers.
 Â
It said the probe will take into account "widespread concerns" about social media, search engines and online retail services.
 Â
Europe has investigated and fined a number of major U.S. tech companies over the past several years.
