The Internet Streaming Media Alliance (ISMA) was a nonprofit corporation operating in the early 21st century to help standardize and explore open standards for streaming media. ISMA was a corporate collective, with participants such as Apple, Cisco and Sun Microsystems.
In conjunction with other groups, the Internet Streaming Media Alliance helped to develop standards for different audio and video formats, including MPEG formats, over IP networks.
Creating specifications, doing testing and communicating with members, ISMA helped to form some of the common practices for broadcasting over the Internet.
In 2010, Reuters reported that ISMA was merging with MPEG Industry Forum or MPEGIF, another party involved in handling streaming video standards. MPEGIF describes itself as a forum to exchange information and a party in the production of universal media formats and compression standards.
