standard 2D input, but its effectiveness is limited in the matter of depth. Each of the TV manufacturers would design its own 3D glasses in accord with its own 3D television technology. Although the only option available in 2010 was active shutter technology, TV manufacturers (notably LG and Vizio) in mid to late 2011 would offer passive circular polarized glasses, while Sony announced a 3D technology ostensibly requiring no 3D glasses at all. In 2015 Samsung unveiled an 8K display with glasses-free 3D — then the largest and highest resolution 3D TV of all. Home video Several DVD and Blu-ray releases have already tried their hands at releasing the 3D versions of films by using an anaglyph format. One noted release prior to the advent of digital cinema is the 1982 film Friday the 13th: Part 3 in 3D, but other such films actually shot digitally like Coraline were released on DVD and Blu-ray. Both included 2D and 3D versions and both were packaged with pairs of 3D glasses. The Blu-ray Association ordered a new standard for presenting 3D content on Blu-ray that would also be backwards compatible with all 2D displays. In December 2009, it was announced that they had adopted the Multiview Video Codec, which would be playable in all Blu-ray disc players even if they could not generate a 3D image. The codec contains information that is readable on a 2D output plus additional information that can only be read on a 3D output and display. A future extension for 4K Blu-ray 3D is currently in development for the hevc codec Broadcasting In 2008, the BBC broadcast the world's first live sporting event in 3D, transmitting an England vs. Scotland rugby match to a London cinema. On April 3, 2010, Sky TV broadcast a Chelsea vs. Manchester United match to around 1,000 pubs in the U.K. ESPN 3D launched on June 11, 2010. On July 1, 2010, N3D became the world's first 24-hour 3D channel. 25 matches of in the 2010 FIFA World Cup soccer tournament were broadcast in 3D.
