Years ago, I read an article about the period during which regime changes happened in Eastern European countries in the late 1980s and early 1990s. It was mentioned in the article that, in one of those countries, citizens began to put their TVs in front of the windows to give the message that the propaganda and false news no longer worked. Which country was it?
I don't need a source, but it would be great if someone included one in their answer.
