The big tech companies have been on the receiving end of a wave of criticism from all corners, much of it relating to their size and market power. Antitrust suits are being filed and lawmakers are holding hearings.

Now we have a bi-partisan group in the House, of all places, introducing a package of bills that would beef up antitrust laws that would impact companies such as Amazon, Apple, Facebook and Google:

Amazon, Apple, Facebook and Google could be forced to overhaul their business practices under an expansive set of antitrust reforms introduced by a bipartisan group of House lawmakers on Friday.

The package of five bills, draft versions of which were reported by CNBC and other outlets, would make it harder for dominant platforms to complete mergers and prohibit them from owning businesses that present clear conflicts of interest. The legislation represents the most comprehensive effort to reform century-old antitrust laws in decades.

The pressure is mounting and it will be interesting to see the details.
