Where the World’s Data is Stored, and Who Owns It [Infographic] Earlier this week, I came across a fantastic infographic titled Where of Where is the World’s Data Being Stored? Created by Mozy, one of the world’s largest online backup services, the infographic illustrates data stored over the course of 20 years (1986 to 2007). Interesting to note how the year 2000 was about the time we started storing things digitally. Data accounted for in this infographic is stored on hard drives (52%), optical storage (28%), digital tapes (11%), and other formats (9%). This ever-growing myriad of storage options clearly shows our desire to archive everything and our obsession with data security. It goes without saying that datacenters are huge! 295 Exabytes of data was stored worldwide during the 20 years studied. With that being said, enjoy the clever display of the world’s data in this week’s infographic.

Over the last few months we’ve been kept busy with designing visualizations for the project “Ville Vivante”. Based on the premise that the mobile phone has become the center of our everyday communication and main source of information, the City of Geneva, in cooperation with the Lift conference, decided to take the challenge to visualize the digital traces created by our mobile phones. As implied by the title “Ville Vivante” – “Living City” –, the goal of the project was to visualize the urban flow of everyday life and make it visible to passersby at the local trainstation. Our assignment was to craft a given dataset into an animated visualization and a series of posters. While the general setup and goal were clear, we were very free in terms of the actual realization.
In this post I want to show you our attempt to reveal the vividness of a city with a bunch of numbers and to bring a dataset to life.
