The Justice Department is expected to file a lawsuit Tuesday alleging that Google has been abusing its online dominance in online search to stifle competition and harm consumers. The litigation marks the government’s most significant act to protect competition since its groundbreaking case against Microsoft more than 20 years ago. The suit could be an opening salvo ahead of other major government antitrust actions, given ongoing investigations of major tech companies including Apple, Amazon and Facebook at both the Justice Department and the Federal Trade Commission.
