SAN FRANCISCO (Reuters) - Calculating the worldwide growth of the Web remains largely a matter of guesswork, more than a decade after the commercial Internet exploded into popular view.
Seeking to standardize global online measurements, comScore Networks Inc. introduced on Friday a new global survey with an estimate that 694 million people, age 15 or higher, used the Internet during March, or around 14 percent of adults.
The survey, called the comScore World Metrix, estimates there are 168.1 million users across four Asian countries -- China, Japan, India and Korea -- or nearly 25 percent of the total online population. By contrast, the United States is home to 152 million users, or 22 percent of the world's Web users.
