In case you haven't heard about the new Google Books Ngram viewer yet you better check it out now, it is without a doubt the coolest public data application Google has launched since Google Trends.

As you might know, Google has been busy scanning books for the past few years and its database now contains over two billion words from 5.2 million books published over the last 200 years. That's pretty cool in itself, however the Google Books Ngram viewer lets you search that database for the appearance of certain words and then graph them over time to reveal trends.

Mentions for the word 'violence' pretty much flatline until the event of the Television and then receive another boost with the arrival of video and online.

Looks like there has been a steady increase in 'flooding', 'landslide' and 'tsunami' mentions over the past few hundred years but we only recently started talking about climate change.

You have to wonder what all these problems are people are writing about but there definitely seems to be less and less solutions.

Oh well, the days of the horse are definitely over but the car is experiencing a bit of a revival, exceeding second world ware level.
