RealNetworks, Inc. is a provider of online streaming media delivery software and services based in Seattle, Washington, United States. The company also offers subscription-based online entertainment, entertainment and mobile messaging services. Real Networks (then known as Progressive Networks) was founded in 1994 by Rob Glaser, former CEO of Microsoft, and a management team including Barrett, Sedless Andy, and Stephen Buerkle. The company's original objective was to provide a distribution channel for politically progressive content. It has evolved into a technological project to utilize the Internet as an alternative distribution method for audio broadcasting. Progressive Networks became RealNetworks in September 1997. Real Networks was a leader in the streaming media markets and broadcast one of the earlier audio events online, a baseball game between the New York Yankees and the Seattle Mariners on September 5, 1995. They announced the broadcast of video technology in 1997. According to some accounts, by 2000 more than 85% of the flow of content on the Internet was in real form. Despite this success, problems arose because Real Madrid's core business model depended on the sale of streaming media server software, and Microsoft and Apple were giving these products. As servers from Microsoft and Apple became more capable, SR server sales inevitably eroded. On January 20, 2000, RealNetworks filed an injunction against Streambox, Inc. in relation to the above-mentioned products that were designed to convert Real Audio files (.rm) into other formats. On December 4, 2001, the company was expected to launch its first coordinated effort to sell music It is delivered from major online labels and is part of a broader initiative by the company to develop Internet services targeting Internet users with fast Internet connections. In 2002, a strategic alliance was formed between RealNetworks and Sony to expand collaboration.
