Google loses massive U.S. antitrust case over its search dominance

WASHINGTON (AP) -- A judge on Monday ruled that Google's ubiquitous search engine has been illegally exploiting its dominance to squash competition and stifle innovation in a seismic decision that could shake up the internet and hobble one of the world's best-known companies.

The highly anticipated decision issued by U.S. District Judge Amit Mehta comes nearly a year after the start of a trial pitting the U.S. Justice Department against Google in the country's biggest antitrust showdown in a quarter century.

After reviewing reams of evidence that included testimony from top executives at Google, Microsoft and Apple during last year's 10-week trial, Mehta issued his potentially market-shifting decision three months after the two sides presented their closing arguments in early May.

"After having carefully considered and weighed the witness testimony and evidence, the court reaches the following conclusion: Google is a monopolist, and it has acted as one to maintain its monopoly," Mehta wrote in his 277-page ruling.

It represents a major setback for Google and its parent, Alphabet Inc., which had steadfastly argued that its popularity stemmed from consumers' overwhelming desire to use a search engine so good at what it does that it has become synonymous with looking things up online. Google's search engine currently processes an estimated 8.5 billion queries per day worldwide, nearly doubling its daily volume from 12 years ago, according to a recent study released by the investment firm BOND.

Google almost certainly will appeal the decision in a process that ultimately may land in the U.S. Supreme Court.

For now, the decision vindicates antitrust regulators at the Justice Department, which filed its lawsuit nearly four years ago
