All told, worldwide internet traffic will quadruple as the developing world continues to log on.
By 2015, Asia will surpass North America in monthly internet usage, according to a study released by Cisco Systems. While North America reigns supreme today, with more than 9,000 petabytes (1 petabyte = a million gigabytes) crossing networks every month in 2011, Asia is expected to use up more than 24,000 a month by 2015, compared to North America’s forecasted 22,000. The Middle East/Africa will also replace Latin America as the fastest-growing sources of internet traffic by 2015. The study predicts that worldwide internet traffic will quadruple over the next five years as more and more users turn to the web for video content through such services as Netflix.
