Six bipartisan anti-Big Tech bills passed at the committee level Thursday and now head to the House floor, marking Washington’s most significant and serious attempt to reshape the technology industry.

The six sweeping antitrust bills aimed at reining in tech giants such as Apple, Amazon, Google, and Facebook passed the House Judiciary Committee on Thursday by narrow bipartisan margins after over 24 hours of debate and over a year of investigations into anticompetitive practices in the tech industry by the panel.
