BBC published an interactive map showing the growth of broadband
connection from 1999 to 2011.
Canada seems to be the earliest country that the broadband is populized. In Asia, South Korea is the early bird, even earlier than Japan (Let's utter a deep sigh for North Koreans).
It is really a great archievement for China - although until now maybe just around 10% of inhabitants in China are using broadband, don't forget that means more than 100 million... while at the same time let's sigh again out a greater thing in China: GFW.
Plus, see the submarine broadband cables, Hong Kong is definitely a hub of communication to the world, as it has always been for more than 100 years.
