Posted by Celia Walter | 24 May, 2011...
- Facebook: users submit around 650,000 comments on the 100 million pieces of content served up every minute on its site.[1]
- YouTube: every minute, over 35 hours of video are uploaded to the site.[2]
- eBay is now the world’s largest online marketplace with more than 90 million active users globally and $60 billion in transactions annually, or $2,000 every second.[3]
- Google: 34,000 searches per second (2 million per minute; 121 million per hour; 3 billion per day; 88 billion per month)[4]
- Twitter already has 300 million users producing 140 million Tweets a day, which adds up to a billion Tweets every 8 days[5] (@ 1,600 Tweets per second)
- Apple: more than 3 billion apps have been downloaded from its App Store by customers in over 77 countries.[6]
- Yelp: as of March 2011 the site hosted over 17 million user reviews.
- “Humankind shared 65 exabytes of information in 2007, the equivalent of every person in the world sending out the contents of six newspapers every day.”[7]
- Researchers at the San Diego Supercomputer Center at the University of California, San Diego, estimate that, in 2008, the world’s 27 million business servers processed 9.57 zettabytes, or 9,570,000,000,000,000,000,000 bytes of information. This is “the digital equivalent of a 5.6-billion-mile-high stack of books from Earth to Neptune and back to Earth, repeated about 20 times a year.” The study also estimated that enterprise server workloads are doubling about every two years, “which means that by 2024 the world’s enterprise servers will annually process the digital equivalent of a stack of books extending more than 4.37 light-years to Alpha Centauri, our closest neighboring star system in the Milky Way Galaxy.”[8]
