What type of speech is often legally protected under freedom of speech?

Commercial speech is often legally protected under freedom of speech because it relates to the advertisement and promotion of products and services, provided that it is not misleading or deceptive. This type of speech is regulated but must still be balanced against First Amendment rights. The U.S. Supreme Court has recognized that commercial speech serves an important function in the marketplace of ideas, as it informs consumers and promotes competition.

While other forms of speech may not enjoy the same level of protection or may be subject to restrictions, commercial speech benefits from a degree of constitutional safeguard, particularly when it conveys truthful information about lawful goods and services. Regulations about commercial speech typically address false or misleading claims, rather than prohibiting the speech altogether.
