On Tuesday, the Justice Department and 11 state attorney generals filed an antitrust lawsuit accusing Google of preserving its monopolies in search and search advertising with anticompetitive behavior. The suit, filed in a Washington, D.C., federal court, is the most significant antitrust action targeting a tech company in decades. 

The case alleges that Google, an Alphabet subsidiary, has maintained its central role in search and advertising through anticompetitive contracts which allowed Google to establish itself as a gatekeeper to the digital world and its economy, giving it even greater latitude to deal with any potential competitors.
