Social networks have seen explosive growth in recent years, with 2 out of every 3 people online visiting a social network in 2006. Large companies are recognizing the importance and profitability of social media, with advertising spending on social networks forecast to reach $61 billion by 2012. While large corporations will take time to implement campaigns, small and medium businesses are quickly moving to leverage social networks for marketing.
