The article is here; the Introduction:
On my bookshelf is a treasured relic of a bygone age, a full print edition of The Oxford English Dictionary (OED): twelve volumes plus five supplements, the last of them published in 1986. The OED puts the first use of journalism, "the occupation or profession of a journalist; journalistic writing; the public journals collectively," at 1833. Journalistic, "of or pertaining to journalists or journalism; connected or associated with journalism," arrived a few years earlier, in 1829. Reporter, "one who reports, debates, speeches, meetings, etc., especially for a newspaper; a person specially employed for this purpose," originated earlier still, in 1813. And interview, "to have an interview with a person; specifically on the part of a representative of the press," didn't appear until decades later, in 1869.
I served as dean of Columbia University's Graduate School of Journalism for ten years, from 2003 to 2013. During that time, I was privileged to attend dozens, or maybe even hundreds, of official journalism events: banquets, prize ceremonies, and so on. Almost invariably, the speakers would extol the First Amendment as a sacred constitutional enshrinement of our profession. Often one of them would observe that we are the only field of endeavor specifically mentioned in the Constitution, or assert that it was the framers' special intent to put the amendment that mentioned us first because it was so important to them.
But as we see from the OED, such sentiments are self-celebratory historical fantasies, because there were no journalists in 1791, when the First Amendment was ratified. At the Constitutional Convention, in 1787, the framers specifically declined to include a press freedom clause in the original document, which is why the First Amendment, along with the rest of the Bill of Rights, was added a few years later by Congress. In the original version of the Bill of Rights, the current First Amendment was actually the Third Amendment, in line behind two others that were dropped because they couldn't attract majority support.
