LinkedIn is often the first thing that comes to mind when marketers think about social media for business-to-business (B2B) companies. Today, the popular B2B social network announced that it hit a major milestone, surpassing 100 million users and counting. The company, founded in December 2002 and launched in May 2003, reached profitability fairly soon, and its growth has been accelerating over the past few years.
It took LinkedIn six years to reach 50 million users, but it only took a year and a half for the business social network to double that number. LinkedIn hit 85 million members in October 2010 and revealed that it had more than 90 million users when it filed to go public earlier this year.
LinkedIn is now growing at about one million users per week, with a new professional joining the site every second. LinkedIn is growing globally with more than half of its users outside of the U.S., located in more than 200 countries and territories around the world.
To celebrate its new achievement, the LinkedIn team has created this interesting infographic breaking down its growth and its overall membership. It comes with several interesting facts on who uses LinkedIn and even when they use it.
