In 2005, Google estimated the internet contained some 5 million terabytes of data - that's more than 1 gigabyte for each of Earth's 4.5 billion trips around the sun.There are simpler ways to appreciate the internet's sheer scale. Recent estimates suggest that well over 1 billion people rely on computers to access the internet (see graphics of internet traffic in 2002, 2004, 2006 and 2008). Yet there are also a billion or so other people who use cellphones to visit cyberspace, making them as much a part of the online community as someone surfing from a PC.Explore the exploding internet with our gallery of mapsThat the internet is vast is undoubted. In July 2008, web surfers were introduced to Cuil.com, billed by its designers as "the world's biggest search engine". It indexed an impressive 120 billion pages, but shortly before its launch Google announced that its systems had registered a trillion unique pages (see Internet census 2007 and 2008).Even this might represent a fraction of what is out there. Some estimates suggest that there could be hundreds of times more information stored on the internet than Google or Cuil have so far indexed.One thing's for sure: the internet and its contents will continue to grow rapidly. According to Google, several billion web pages are added each day. And in the minute it has taken you to read this, the total has leapt by about 700,000.
