Defamation is a creature of common law, predating the United States but hugely changed in the 20th century by the Supreme Court interpreting the 1st amendment. Prosser (textbook read far and wide by 1Ls everywhere) says that the big cases are: NYT v Sullivan, 376 US 254 (1964); St. Amant v Thompson 390 US 727 (1968); Masson v New Yorker Magazine 501 US 496; and Gertz v Robert Welch 418 US 323. When the detailed punditry discuss this they talk about some of the same cases.
