Enterprise 2.0 refers to the use of Web 2.0 technologies within an organization to enable collaboration and streamline business processes. It aims to help employees, customers, and suppliers share and organize information through social media tools. The document traces the evolution of collaboration from face-to-face meetings and paperwork in 1960 to today's virtual collaboration enabled by tools for instant communication, blogging, microblogging, crowdsourced content, and secure collaborative spaces with features like profiles, communities, blogs, and file sharing. While new technologies enable collaboration, an idea or issue is still crucial to drive collaboration within an organization.
