Answer:
enterprise social
Explanation:
Enterprise social networks (ESN) refer to an internal privately owned social network that includes only the members of an organization. E.g. a F@cebook only for people that work on F@cebook.
The purpose of having an enterprise social network is to improve communication and networking among the organization's members. ESN were popular a few years ago, but lately they have been set aside and they lost a lot popularity. People are too busy on their normal social networks to also have to worry about their work social networks. The only exception to this failure is probably Wh@tsapp that continues to be extremely popular within work groups.
