"Congress shall make no law . . .," the First Amendment commands, "abridging the freedom . . . of the press." But Congress, the Executive Branch, and the courts have promulgated a host of laws governing both print and electronic media. This survey of mass media law explores such current topics as prior restraints on publication, defamation, privacy, newsgathering liability, media liability for unlawful conduct of third parties, compelled disclosure of sources, and access to information. Practical aspects of representing media clients are examined along with public policy implications of existing legal doctrines and proposals for change.
