The study, conducted by Towers Watson, asked 290 organisations from across America, Europe and Asia about their internal communications behaviours.
It found that more than 50% of them are currently using social media tools as part of their internal communications.
The most popular tool was instant messaging, which was used by 77% of those surveyed. This was followed by streaming audio and video, which was used by 61%.
Other tools in the mix included employee blogs, employee profiles and social networks.
"We believe that social media can be a great tool for communicating with employees in the workplace," said Kathryn Yates, global leader of communication consulting at Towers Watson.
"By its nature, social media is designed to build community and could help engage employees on key topics such as performance, collaboration, culture and values," Yates said.
Despite more organisations adopting social media tools internally however, the usage of such platforms remains low amongst employees.
A report released last year revealed that just 13% of IT professionals believed their internal social networks were successful.
