The year saw major changes at sites like Facebook and Twitter as millions of non-technical users became regular users of social networks. The user base of social networks this year expanded greatly from the traditional teenage and college student set. It now includes many of their parents and even grandparents who now use the technology as a primary mode of communication.
Perhaps most significant is that companies in various industries startedfacebook to see how social networks can help boost business even in a recession. While many CEOs may still be a bit disconnected from the social networking phenomenon, many companies, like Zappos.com and Dell Inc., have found ways to draw in new customers using Web 2.0 methods.
All this growth did have to come at someone's expense, and that burden seems to have fallen on MySpace. A pioneer in the social networking scene and an early market leader, MySpace's share fell behind Facebook globally and in the U.S. this year for the first time. Facebook's share of the U.S. market reached 30.26% in September while MySpace's September share plunged 55% to 30.26% from a market leading 66.84% share a year earlier, according to Experian Hitwise.
