Oh yes, definitely the internet plays a huge roll in the world we have today, probably a bigger roll than 9/11. Humanity has seen and adapted to large scale tragedies before, but this is the first time we've had the internet. But of all the variables, 9/11 is a big one in the US. It also showed the media and advertisers how much more money there was to be made from these events. Ever since 9/11 the news media has been hard at work developing new ways to milk sensationalism junkies the same way that mobile companies milk gaming addiction whales.
