Summary

Antitrust, also known as competition law, is a field dedicated to promoting and maintaining market competition by regulating anti-competitive business practices. Its history dates back to the Roman Empire, and it has become increasingly globalized since the late 20th century. The United States and the European Union possess the most influential regulatory systems. While national competition laws primarily focus on domestic markets, they can extend extraterritorially based on the 'effects doctrine,' and international competition is addressed through agreements like those under the World Trade Organization. Contemporary discussions highlight antitrust concerns in areas such as media consolidation, exemplified by the bidding war for Warner Bros. Discovery, and the growing influence of user-generated content platforms like YouTube and TikTok.

Competition law

Competition law is the field of law that promotes or seeks to maintain market competition by regulating anti-competitive conduct by companies. Competition law is implemented through public and private enforcement. It is also known as antitrust law (or just antitrust), anti-monopoly law, and trade practices law; the act of pushing for antitrust measures or attacking monopolistic companies (known as trusts) is commonly known as trust busting. The history of competition law reaches back to the Roman Empire. The business practices of market traders, guilds, and governments have always been subject to scrutiny, and sometimes severe sanctions. Since the late 20th century, competition law has become increasingly global. The two largest and most influential systems of competition regulation are United States antitrust law and European Union competition law. National and regional competition authorities across the world have formed international support and enforcement networks. Modern competition law has historically evolved on a national level to promote and maintain fair competition in markets principally within the territorial boundaries of nation-states. National competition law usually does not cover activity beyond territorial borders unless it has significant effects at the nation-state level. Countries may allow for extraterritorial jurisdiction in competition cases based on so-called "effects doctrine". The protection of international competition is governed by international competition agreements. In 1945, during the negotiations preceding the adoption of the General Agreement on Tariffs and Trade (GATT) in 1947, limited international competition obligations were proposed within the Charter for an International Trade Organization. These obligations were not included in GATT, but in 1994, with the conclusion of the Uruguay Round of GATT multilateral negotiations, the World Trade Organization (WTO) was created. The Agreement Establishing the WTO included a range of limited provisions on various cross-border competition issues on a sector specific basis.
