Microsoft has acquired Yammer in a bid to make its range of software products more appealing.
The four-year-old business has around five million users and is a social networking site for communication within companies.
Last year Microsoft bought Skype, and is currently integrating it into a selection of its products, including its most popular software Office. Yammer could be the next business to see itself become a new feature in Microsoft products.
Bought for $1.2 billion (£770 million), Yammer was created in 2008 by PayPal founder David Sacks. Dubbed ‘Facebook for the workplace’, it is a messaging tool for colleagues, enabling companies to create a private social network for employees.
"When we started Yammer four years ago, we set out to do something big. We had a vision for how social networking could change the way we work,” commented Sacks.
“Joining Microsoft will accelerate that vision and give us access to the technologies, expertise and resources we'll need to scale and innovate."
