A wonderful collection of digital/mobile/social stats pulled together by Mary Meeker. A full 117 slides of statistic fun.
One of my my favourite stats. Mobile traffic made up 15% of all internet traffic in the whole world in May 2013. And it is obviously only going one way.
The adoption of smartphones in China is extraordinary as is the fact that mobile search surpassed desktop search in South Korea at the end of 2012.
