The purpose of this paper is to help identify newspaper advertisements which fall under the protection of the First Amendment. Although the Supreme Court declared in 1942 that advertisements which propose a purely commercial transaction were not protected by the First Amendment, in 1976 it decided that commercial expression, like other forms of expression, is not wholly without the right to freedom of speech and press. Newspaper advertisements are, however, still subject to restrictions of time, place, and manner of publication. Certain types of advertisement (such as that by doctors, lawyers, etc.), misleading advertisements, advertisements which propose illegal transactions, and obscene or inherently offensive materials are also prohibited.
