Twitter Chief Executive Jack Dorsey defined one of the company's missions as being the "people's news network," according to an internal memo seen on Monday.
The 10-year-old social networking service has long struggled to define its core purpose and is under the spotlight as it explores selling itself in a process that has attracted potential buyers such as Salesforce.com.
Twitter has made a recent push into news and sports on mobile devices and this foray could pique the interest of a media company as an acquirer, analysts have said.
The memo does not address the sales process. Twitter did not immediately respond to a request for comment.
