Doesn't make it any more likely to be correct.
I suppose it could be that it just seems that way, since popular media is everywhere, and are always hungry for a good (or even mediocre) story.
This is not that far off from what I think is the case.
I'm gonna draw a parallel to natural disasters. There seem to be quite a lot of them occurring, thus people start believing that it's because us humans and such and such (part of that may be true, I don't know). But, it's not so much that we have more of them now than ever, as much as we are more aware of what's going on than ever before.
When it comes to prophecies it's kind of the same deal. People in general are more aware of various things in todays world, being privvy to radio, tv, internet and being able to read. It's easier for information, not to mention mis-information, to spread in todays society.
