Datelined “Los Angeles,” the news story began, “Social media has been buzzing for weeks...” Has they? I thought. Who would use the word “media” as if it were singular? The answer, of course, was anyone who had not been taught the difference between the two words, both derived directly from Latin (“media” is plural — always; a “medium” is singular). For example, Facebook and Twitter are social media; Facebook by itself is a social medium.
As for those who were not taught the difference it is probably a large number of people, inasmuch as few public schools today teach spelling and word definitions, let alone grammar and sentence structure. In this case, though, the article was written by an Associated Press reporter who should know better. If not, his or her copy editor should have caught it. Either the writer or the copy editor are probably graduates of a journalism school. Alas, those schools seem indifferent to whether their students become proficient in English language usage.
