I picked up this book called Honey, I Shrunk the World from Crosswords last month and it has helped me get a lot of insight into digital media. If you are looking for a book about internet usage statistics and digital trends, I would recommend Honey, I Shrunk the World to you. The book if full of interesting definitions, digital tools, country wise break up of online usage behaviour, demographic data, online advertising, social media activities and other interesting statistics.
The book also has population and economic statistic, along with internet and mobile statistics for countries which is a great help for e-commerce understanding in different regions. The section also shares the major languages spoken in that country.
It also gives a list of top 100 websites, blogs and web products. It was interesting to see the awards section too. There is data on the Digital Media Awards, GOAFAST, Cannes Lions, Webby awards. There are lots of tools out there like the Google Ad Planner, comScore, Alexa etc that can provide some of this data but it’s great to have just one resource where all this data is available.
