3. Federal Trade Commission Act (1914):

   • Alongside the Clayton Act, the Federal Trade Commission Act created the Federal Trade Commission (FTC) as an independent agency to investigate and enforce antitrust laws.

4. Robinson-Patman Act (1936):

   • The Robinson-Patman Act amended the Clayton Act to address price discrimination. It aimed to prevent anticompetitive practices by prohibiting certain types of discriminatory pricing, such as offering different prices to different buyers when the effect may substantially lessen competition.

5. Celler-Kefauver Act (1950):

   • The Celler-Kefauver Act, also known as the Antimerger Act, amended the Clayton Act to address anticompetitive mergers and acquisitions. It empowered the government to scrutinize and challenge mergers that might substantially lessen competition.

6. Antitrust Division of the Department of Justice (1903):

   • The Antitrust Division of the Department of Justice was established to enforce antitrust laws and investigate anticompetitive practices. It plays a key role in prosecuting violations of antitrust laws.

7. Chicago School and Consumer Welfare Standard (20th Century):

   • In the latter half of the 20th century, the Chicago School of economics influenced antitrust enforcement. The focus shifted toward a more economic approach, emphasizing consumer welfare as the primary goal of antitrust laws. This led to a greater emphasis on assessing the impact of anticompetitive practices on consumers.

8. Microsoft Antitrust Case (2001):

   • The U.S. Department of Justice and several states brought a landmark antitrust case against Microsoft, accusing the company of anticompetitive behavior by engaging in monopolistic practices. The case resulted in a settlement that imposed restrictions on Microsoft’s conduct.

9. Sherman Act Section 2 Enforcement Guidelines (2008):

   • The U.S. Department of Justice issued guidelines on the enforcement of Section 2 of the Sherman Act, addressing monopolization and attempts to monopolize. The guidelines emphasize the importance of protecting competition and consumers.

10. Recent Antitrust Investigations (2010s-present):

    • In recent years, major tech companies have faced increased scrutiny over antitrust concerns. Investigations and hearings have focused on the market dominance of companies like Google, Facebook, Amazon, and Apple, leading to debates about the effectiveness of existing antitrust laws in the digital age.

Antitrust law in the United States continues to evolve, responding to changes in the economy and technological landscape. Ongoing debates surround the enforcement of antitrust laws and their application to modern industries.
