Not to be outdone by the other web metrics companies releasing their traffic analysis articles in the last few days, Comscore announced today that “Social Networking Explodes Worldwide“, citing a 25% growth worldwide in the last year.

Naturally, the growth is largely coming outside of North America whose 9% growth rate for the year is the lowest globally and emerging internet markets were responsible for most of the growth.

Additionally, they released information about specific sites showing MySpace nearly stalled at 3% growth with Facebook and Hi5 the fastest growing social networks at the moment. Also of interest to the social media marketer is that they are showing Facebook as having overtaken MySpace in monthly uniques. But then again, only a blind social media marketer wouldn’t have noticed Facebook’s meteoric rise.
