Peer-to-peer video sharing was introduced by Nokia phones first in 2004. This was a proprietary solution on top of a SIP or IMS infrastructure. Some European operators offered commercial services based on these phones already in 2005. Similar services popped under the names of See What I See, Rich Voice Call, Push-to-Video (P2video or PTV), etc.
The GSMA Video Share service was originally defined, implemented and tested during the Session Initiation Protocol (SIP) trials conducted by the GSM Association in 2005/2006. During the SIP trials, the Video Share service used to demonstrate IMS interworking over SIP. Video Share was also tested on the IPX to prove that the service might become universally available in the future.
Subsequently, GSMA decided to create a separate project for Video Share. Phase 1 of the Video Share project built on and leveraged the results from the SIP trials. Service definition for the first phase of the Video Share project was completed in September/October 2006. Mobile operators worldwide, such as AT&T, have deployed the Video Share service based on the Phase 1 service definition. An interoperability technical reference specification for Video Share is also available from GSMA.
Phase 2 of the GSMA Video Share project was kicked off in May/June 2007 and is currently in progress.

Famous quotes containing the word history:
“Philosophy of science without history of science is empty; history of science without philosophy of science is blind.”
—Imre Lakatos (19221974)
“There is no example in history of a revolutionary movement involving such gigantic masses being so bloodless.”
—Leon Trotsky (18791940)
“Postmodernism is, almost by definition, a transitional cusp of social, cultural, economic and ideological history when modernisms high-minded principles and preoccupations have ceased to function, but before they have been replaced with a totally new system of values. It represents a moment of suspension before the batteries are recharged for the new millennium, an acknowledgment that preceding the future is a strange and hybrid interregnum that might be called the last gasp of the past.”
—Gilbert Adair, British author, critic. Sunday Times: Books (London, April 21, 1991)
