A great book for anyone interested in U.S. mass communication law, covering topics such as First Amendment guarantees, libel and slander in mass communication, privacy, obscenity, freedom of the press, commercial speech and FCC regulation of mass media, explained through U.S. Supreme Court decisions (v.g., New York Times Co. v. Sullivan, Miller v. California, New York Times Co. v. United States). Specially interesting is the discussion about content restraint of motion pictures (chapter IV) and TV (chapter XI), the latter an issue back on newspapers after a recent Supreme Court decision (United States v. Playboy Entertainment Group, Inc.).
