Even mass media wasn't the beginning of it. There's lots of examples to look at in history of "outrage" that spread through a huge part of the world, for example inquisitions or witch trials. Slower, but I'm sure if you thought harder or had better knowledge of history than me you could come up with examples of things that happened before even the printing press was invented. There's probably plenty of examples in Roman history that spread out from Rome to its conquests.
