From David Wise’s cover story, The President and the Press in the April 1973 issue:
The First Amendment clearly protects the printed press. But the Founding Fathers, after all, did not foresee the advent of television, and the degree to which broadcasting is protected by the First Amendment has been subject to shifting interpretation. Technology has outpaced the Constitution, and the result is a major paradox: television news, which has the greatest impact on the public, is the most vulnerable and the least protected news medium.
