It’s hard to imagine an American industry as privileged and protected as the newspaper. Right there in the First Amendment to the Constitution, are the words: “Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press…” No other industry is mentioned in the Constitution.
The rights of journalists, working in print or electronic media, have been protected down through the years. While ordinary citizens might be liable to be sued for libel, the U.S. Supreme Court in 1964 set a higher standard in Times v. Sullivan so that a newspaper could be sued only if it could be proved the paper knew ahead of time that what it was printing was false.
In any other industry, the concept of competitors combining operations might be anathema to rigorous antitrust law (admittedly a stale concept after the past eight years).
