Was 2011 the year of social media?

Facebook now commands more than 800 million active users, adding more than 200 million of those in the last year alone. Twitter now boasts 100 million active users, about a fifth of whom are in the USA. LinkedIn has 64 million users in North America alone, and used this tally to launch a successful IPO back in May.

Moreover, these social platforms also now play a major role in the way that we receive and share news, as well as becoming an important, on-the-spot source of news themselves.

Internet marketing firm Dream Systems Media took data provided by AdAge and converted the numbers into infographic, which takes a closer looker at today’s social media statistics.
