You often hear people say things along the lines of, “Never read the comments!” Well, that’s definitely not true for NOOBs, whose comments and commenters are frequently brilliant. Just a few days ago, “oldyellr” commented on the “petrol” entry: “Sadly, Britishisms are infiltrating North American language because somebody thinks they’re ‘cool’. Examples are ‘mobile’ for cellphone and ‘CCTV’ for surveillance video.” The brilliant bit wasn’t oldyellr’s comment but “Michael M”‘s response: “They are? If only there was some website that pointed these out.”
oldyellr, missing the humor, carried on: “You don’t need a website or Google. Just listen to the news and how people talk today. But if you like, here is just one link.” The link was to a BBC article that cited Not One-Off Britishisms and quoted me.
I bring this up, actually, not to have sport at oldyellr’s expense but to thank him (I think he’s a he) for an idea for a post. Not “mobile,” which I covered years ago and continues apace, but his other example. When I started visiting London regularly, in the mid-1990s, I noticed many references in the press to CCTV, an initialism for closed-circuit TV, in this case specifically referring to surveillance cameras. The OED’s first two citations for the term, from 1959 and ’60, are from American publications. I believe I can antedate that by one year with a quote from Radio & TV News, also American:

According to Google Books Ngram Viewer (whose reliability goes up only to 2000), the term was used with roughly equal frequency on both sides of the Atlantic through the early ’90s, when, consistent with my experience, it shot up in Britain:

I don’t know why that happened and would be curious about any ideas. It doesn’t appear to be because of a preponderance of CCTV use in the U.K. According to Wikipedia, estimates of the number of such cameras in operation there are between 1.85 million and 4.2. million, while the figure cited for American is 30 million.
The terminological discrepancy was still present in the early 2010s, when “CCTV” was used about ten times more frequently in Britain than in the U.S. (and Canada), according to another database, the Corpus of Global Web-Based English.

But as oldyellr perceived, things seem to be changing just a bit. According to yet another database, the Corpus of Contemporary American English (COCA), the use of the term in the U.S. rose roughly tenfold between 2000 and 2017, from .08 uses per million words to .80:

Here are some examples from COCA, all from 2017:
So “CCTV” appears to be established in America, and on the rise.
If only there were a website that pointed such things out.
