How Google fares in the landmark antitrust trial will have huge regulatory implications for fellow tech giants Amazon, Apple, and Meta.

Google’s antitrust case is the most consequential since Microsoft faced comparable DOJ scrutiny in the late '90s.

DOJ lawyers have even argued that the ruling against Microsoft at the time paved the way for Google and Apple to become the behemoths they are now, the AP reported. Microsoft settled in 2001 after agreeing to restructure its business.

The DOJ filed an antitrust suit against Apple in March, alleging that the iPhone maker was suppressing app development and worsening the quality of cross-platform messaging, among other claims.
