A landmark antitrust case involving Google and the U.S. government is drawing parallels to the historic legal battle between Microsoft and federal regulators.
The recent ruling by a federal judge that Google operated as a monopoly by stifling competition in the search engine market has sparked a debate over potential penalties for the tech giant.

Legal experts suggest that the Microsoft case from a quarter-century ago has set a precedent for the current antitrust scrutiny faced by Google, shaping the landscape of antitrust law in the tech industry.
The case against Microsoft in the late 1990s accused the software giant of monopolizing the personal computer market, leading to significant legal repercussions that continue to influence antitrust enforcement today.
The findings of the Microsoft case, which accused the company of bundling its Internet Explorer browser with its Windows operating system to stifle competition, are being revisited in light of the current Google antitrust case.
Legal scholars note that the actions taken against Microsoft, including the proposed breakup of the company, have laid the groundwork for the ongoing debate over Google’s market dominance.
