I think that's a contributing factor, but I don't think it's the only one. We live in the age of social media where anybody anywhere can post anything at any time. Anybody can be a journalist and post pictures, videos, or give live updates as events are happening. In fact we have a lot of people like this from just about every conflict in the world who give us updates just about everyday. Despite this, things like wars are still treated as trends by people. When the fad gets old, people get bored and move on to the next new thing.
