What regulates advertising and encourages informative and truthful advertising?

Advertising is primarily regulated by government agencies such as the Federal Trade Commission (FTC) in the United States, which enforces laws against deceptive practices and promotes truthful advertising. Additionally, industry self-regulatory organizations, like the Advertising Self-Regulatory Council (ASRC), provide guidelines to encourage ethical advertising standards. These regulations aim to protect consumers from misleading claims and ensure that advertisements provide accurate information about products and services.
