BBC News - The top 100 sites on the internet
Explore this interactive graphic to find out which are the biggest sites on the internet, as measured by the Nielsen company. This feature is part of SuperPower, a season of programmes exploring the power of the internet.
The data used to generate the interactive treemap visualisation was collected by the Nielsen company and covers the UK, France, Germany, Italy, Spain, Switzerland, Brazil, US and Australia. The figures represent unique users for the month of January 2010.
The categories – such as retail, social networks, search/portal – were defined by the BBC. Because some websites have more than one use, they could fall within more than one category (e.g. Yahoo). However, the treemap only classifies them once.
The maps were produced using the Prefuse Flare software, developed by the University of California Berkeley.
