The wheels are turning on potentially blockbuster US antitrust investigations into big tech.

Reports in recent days suggest that Apple, Amazon, Facebook, and Google could all face scrutiny after the Federal Trade Commission and Department of Justice carved up which of the big tech companies they would examine.

Politicians on both sides have been ramping up their rhetoric. Elizabeth Warren has made breaking up big tech the rallying cry of her presidential candidacy campaign, and Republican lawmakers have laid into the Silicon Valley elite for perceived anti-conservative bias.

There is little detail about the substance of the investigations, but read on to find out what antitrust proceedings could look like for Apple, Amazon, Facebook, and Google companies, and which Trump administration body will take the lead on the probes.
