Overview
RealNetworks is an American technology company headquartered in Seattle, Washington. It is best known for helping establish Internet streaming as a mass-market technology through the RealAudio, RealVideo, RealPlayer, and Helix product families. The company began in 1994 as Progressive Networks, founded by former Microsoft executive Rob Glaser with Phil Barrett, Andy Sharpless, and Stephen Buerkle. Its initial concept involved distributing politically progressive content, but the business quickly shifted toward using the Internet as an alternative channel for audio broadcasting and other digital media. RealNetworks became an early leader in streaming media. In September 1995, it carried an Internet audio broadcast of a baseball game between the New York Yankees and Seattle Mariners, one of the early high-profile live sports streams. The company announced streaming video technology in 1997 and changed its name to RealNetworks in September of that year. It completed an initial public offering on Nasdaq in October 1997 under the symbol RNWK. By the end of the 1990s, Real-format media was widely used across the Web, and the company had become one of the most visible names in online audio and video. The company’s early business centered on selling streaming servers, media software, and related services to broadcasters, enterprises, and content providers. This position came under pressure as Microsoft and Apple incorporated competing media and streaming capabilities into broader operating-system and hardware ecosystems, often distributing them at little or no direct cost. RealNetworks subsequently expanded into consumer subscriptions, digital music, online games, mobile entertainment, messaging, and personal media storage. Its businesses included RealPlayer, RealTimes, Rhapsody, GameHouse, RealArcade, RealDVD, RealDownloader, Helix, and mobile-carrier services. RealNetworks has also pursued technology businesses outside traditional media playback. The company introduced KONTXT, a platform for classifying and managing mobile text messages, and later KONTXT for Voice, designed to help identify and block scam robocalls. In 2018 it launched SAFR, a facial-recognition and computer-vision platform intended for security, access control, public-safety, and commercial applications. SAFR later added functions for recognizing people wearing masks and received a U.S. Air Force grant for artificial-intelligence analytics related to rescue missions, perimeter protection, and domestic search operations. Corporate transactions have shaped the company’s portfolio. RealNetworks acquired the Rhapsody music service from Listen.com in 2003, purchased GameHouse in 2004, bought Dutch casual-game company Zylom in 2006, spun Rhapsody out as a separate company in 2010, and acquired social-casino company Slingo in 2013. Rob Glaser stepped away from the company in 2010 and returned as chief executive in 2012. On December 21, 2022, RealNetworks was taken private by Glaser, ending its period as a Nasdaq-listed public company. It continues to operate as a technology business focused on digital media, artificial intelligence, computer vision, and communications services.
History
RealNetworks was established in 1994 as Progressive Networks by Rob Glaser, a former Microsoft executive, together with Phil Barrett, Andy Sharpless, and Stephen Buerkle. Although its initial purpose was to distribute politically progressive material, the company soon focused on Internet audio broadcasting. This direction reflected the founders’ view that the emerging Internet could provide an alternative distribution system for radio and other forms of recorded or live media. The company’s early technical and commercial progress made it a pioneer in streaming. In September 1995, it transmitted an audio broadcast of a baseball game between the New York Yankees and Seattle Mariners. In 1997, it announced streaming-video technology, changed its corporate name to RealNetworks, and went public on Nasdaq under the symbol RNWK. RealAudio and RealVideo became important formats for Internet publishers, while RealPlayer gave consumers a recognizable application for playing streamed and downloaded media. Around 2000, Real-format content reportedly represented a very large share of streaming material available online. RealNetworks’ main challenge was strategic rather than technological. Its early revenue model depended substantially on selling media-server software and related infrastructure. Microsoft and Apple increasingly offered competing playback and server capabilities as components of their larger software ecosystems, weakening the market for a standalone streaming supplier. RealNetworks responded by developing the Helix platform, pursuing open-source components, and expanding into subscription entertainment and consumer services. The company entered online music and gaming through a series of launches and acquisitions. It acquired Listen.com’s Rhapsody service in 2003 and operated it as RealRhapsody before later separating the business. RealNetworks launched a RealPlayer Music Store in 2004 and experimented with Helix DRM and the Harmony system, which was designed to make protected music playable across multiple device ecosystems. In gaming, it introduced RealArcade in 2001, acquired GameHouse in 2004, bought Zylom in 2006, and later operated its games business under the GameHouse name. The 2013 purchase of Slingo expanded its casual and social gaming portfolio. RealNetworks also entered legally and commercially contested areas. Its RealDVD software, launched in 2008, was intended to let users copy DVD movies they owned. Courts found that the product conflicted with copyright protections and contractual restrictions imposed by the DVD Copy Control Association, and distribution was blocked by injunction. The company separately pursued litigation concerning Real Alternative, an unofficial software bundle that played RealMedia files without RealPlayer. A Dutch court dismissed the case against webmaster Hilbrand Edskes in 2011 and ordered RealNetworks to pay damages; the company later appealed. Consumer media remained important, but the company increasingly diversified into mobile and enterprise technology. RealPlayer Cloud launched in 2013 and was renamed RealTimes in 2015, shifting emphasis toward automatically creating and sharing multimedia “Stories” from personal photos and videos. In 2017, RealNetworks introduced KONTXT for mobile-message classification, followed in 2021 by KONTXT for Voice, aimed at combating fraudulent robocalls. SAFR, introduced in 2018, brought facial recognition and computer vision into the company’s portfolio. Its later development included mask-related recognition features and an artificial-intelligence grant from the U.S. Air Force. Leadership and ownership also changed. Rob Glaser left the chief executive role in early 2010 and returned in July 2012. Rhapsody was spun off in April 2010. On December 21, 2022, Glaser took RealNetworks private. The company therefore transitioned from a highly visible public streaming pioneer into a privately held technology provider with activities spanning digital media, games, mobile communications, artificial intelligence, and computer vision.
