Infographic: Global Internet Traffic Expected to Quadruple by 2015

More

By 2015, about three billion people will be using the Internet, according to data that Cisco provided to Mashable. That's considerably more than are using it right now and will account for about one zettabyte in traffic per year. To give you a sense of how much traffic that is, consider this: A zettabyte is equal to 1,000,000,000,000,000,000,000 bytes, or the same amount of digital data that was on the entire Internet in 2010.

Where is all that traffic going to be coming from? Cisco projects that traffic will more than double in Africa and the Middle East, but those of us in the United States will be using the Internet more often as well, with a projected 5.8 Internet-enabled devices for every one person in the country. 

Mashable assembled all of this data, and more, into the infographic presented below.

Infographics are always a bit of a hodgepodge of statistics culled from a variety of sources. Here, we sort through the clutter and pull out some of our favorite facts and figures:

  • The number of smartphones on the market is expected to grow 194 percent between 2010 and 2015, but, perhaps surprisingly, that's not even close to the projected growth rates for tablets, e-book readers and flat panel televisions. Cisco expects the number of flat panels in the world to jump by more than 1,000 percent between 2010 and 2015.
  • The growth in Internet traffic is attributed to four primary issues: more video, additional users, an increase in the number of devices and increased broadband speed.
  • One million minutes of video -- the equivalent of 674 days -- will traverse the Internet every second.
  • The average fixed broadband speed is expected to have a 4-fold increase from 7 Mbps in 2010 to 28 Mbps.
