The Federal Trade Commission (FTC) has formally ended its legal efforts to prevent Microsoft from acquiring Activision Blizzard, a major video game publisher known for franchises such as Call of Duty. The merger, valued at $69 billion, is one of the largest in the gaming industry. The FTC's decision follows a series of legal proceedings and regulatory reviews in the United States and other jurisdictions. The agency had previously sought to block the deal, citing concerns over potential impacts on competition and consumer choice in the video game market. However, after a federal court declined to issue a preliminary injunction and subsequent appeals were unsuccessful, the FTC has now moved to dismiss its administrative litigation. The statement from the FTC indicated that 'the public interest is best served by dismissing the administrative litigation in this case.' With this development, Microsoft is expected to proceed with the integration of Activision Blizzard, potentially reshaping the landscape of the gaming industry. The deal has also been reviewed and approved by regulatory bodies in other regions, including the European Union and the United Kingdom, after Microsoft made certain commitments to address antitrust concerns.
