I am also American and live in the United States. I don't expect ABC News or anyone else to write as if the entire outside world doesn't exist.

Not to be confused with the other ABC https://www.abc.net.au/, which is Australian centric. It is weird that I now have to think about when I see the acronym, 20 years ago I would have seen it immediately as the ABC in the states, but broadcast TV plays so little role in our life now.
