When I was growing up in the U.S. in the 1970s, 35-40% of an average nightly newscast focused on international stories.

On Twitter, if you want to quote someone else, you say, RT, re-tweet, that person's name, and then what they said before. And it's a way of essentially saying, I'm not saying this, but my friend said this and I thought this was interesting.
