The Economist discusses the wider implications and provides numbers about the growth:
The numbers of internet-connected computers have more than doubled since the end of 2002, to 45.6m, and internet-users have risen by 75%, to 111m. China now has more internet-users than any country but America, and over half of them have broadband (up from 6.6% at the end of 2002). Users of instant computer-to-computer messaging systems have more than doubled, to 87m. Blogsonline personal diaries, scarcely heard of three years agonow number more than 30m. And search engines receive over 360m requests a day.
The spread of mobile telephony has been no less spectacular. At the end of last year China had 393m mobile-phone accounts, nearly 200m more than at the end of 2002 and more than any other country.
