Digital Living Network Alliance (DLNA) (originally named Digital Home Working Group [DHWG]) was founded by a group of consumer electronics companies to develop and promote a set of interoperability guidelines for sharing digital media among multimedia devices. As of June 2015 the organization claims membership of "more than 200 companies".
The group published its first set of guidelines in June 2004. The guidelines incorporate several existing public standards, including Universal Plug and Play (UPnP) for media management and device discovery and control, and widely used digital media formats and wired and wireless networking standards.
