Public information has always been a cornerstone of fair financial markets. Historically, insider trading and information asymmetry plagued markets, giving unfair advantages to those with privileged access. The concept of public information became more prominent with the rise of stock exchanges in the 19th and 20th centuries, and legislative efforts, such as the Securities Act of 1933 in the United States, sought to mandate the disclosure of important financial data to all potential investors.
