The most popular video coding standards used for codecs have been the MPEG
standards. MPEG-1 was developed by the Motion Picture Experts Group (MPEG) in
1991, and it was designed to compress VHS-quality video. It was succeeded in
1994 by MPEG-2/H.262,[5] which was developed by a number of companies,
primarily Sony, Thomson and Mitsubishi Electric.[7] MPEG-2 became the standard
video format for DVD and SD digital television.[5] In 1999, it was followed by
MPEG-4/H.263, which was a major leap forward for video compression
technology.[5] It was developed by a number of companies, primarily Mitsubishi
Electric, Hitachi and Panasonic.[8]

The most widely used video coding format, as of 2016, is H.264/MPEG-4 AVC. It
was developed in 2003 by a number of organizations, primarily Panasonic, Godo
Kaisha IP Bridge and LG Electronics.[9] H.264 is the main video encoding
standard for Blu-ray Discs, and is widely used by streaming internet services
such as YouTube, Netflix, Vimeo, and iTunes Store, web software such as Adobe
Flash Player and Microsoft Silverlight, and various HDTV broadcasts over
terrestrial and satellite television.

AVC has been succeeded by HEVC (H.265), developed in 2013. It is heavily
patented, with the majority of patents belonging to Samsung Electronics, GE,
NTT and JVC Kenwood.[10][11] The adoption of HEVC has been hampered by its
complex licensing structure. HEVC is in turn succeeded by Versatile Video
Coding (VVC).

There are also the open and free VP8, VP9 and AV1 video coding formats, used by
YouTube, all of which were developed with involvement from Google.
