Growth in companies using social media marketing nears saturation

Growth in the social media marketing space is nearing saturation, with the vast majority of businesses already using platforms like Facebook and Twitter for promotion, according to new estimates by eMarketer. The research firm forecasts that 88% of companies with more than 100 employees will use social networks for marketing this year, with that figure set to rise to 91% next year and 92% in 2014. That growth is down from the double-digital rate experienced in previous years, leading eMarketer to question how much growth is left in the market.
