About JW Player

ABOUT JW PLAYER If you’ve watched video in the last 10 years, you already know us. We’re the company that pioneered video on the web and brought it to more people across the globe than anyone else. Today, JW Player provides media professionals with powerful and flexible technology to deliver video, grow their audience and monetize with ads. A venture-backed company based in New York City since 2008, JW offers a unique set of business solutions that integrate with any workflow and prioritize speed, API control, and audience growth across all viewing platforms. JW Player solutions are trusted by broadcasters and digital publishers including WWE, Univision, VICE Media, Hearst, LittleThings and Mashable, and developers around the world have deployed JW Player on domains collectively reaching over one billion monthly unique viewers. From Humble Beginnings In 2005 Jeroen “JW” Wijering was a student in the Netherlands, when he created a small piece of open-source software that enabled images and sound to play on the Internet. He was still in college when his product became the foundation for YouTube, which relied on JW Player until it was acquired by Google. By the time Jeroen presented his own website in an oral exam, the JW Player had, unbeknownst to his professors, gained a global reputation. In November 2007 Jeroen merged JW Player with the New York City digital ad agency LongTail Video, teaming up with industry veterans Dave Otten and Brian Rifkin, and the company was rebranded as JW Player in 2013. Today, JW Player is ubiquitous, having been used by tens of millions of web pages and viewed by billions of people worldwide. A History of Innovation For more than ten years, JW Player has been first to support a host of industry standards — an embeddable player, closed captioning, HTML5 web player, VAST web player, MPEG-DASH. Whether it’s new platforms, devices, streaming or advertising standards, this is an industry that is always evolving. In 2005, before smartphones were in every pocket, who could have predicted the dramatic adoption of mobile streaming? Similarly, no one can predict exactly what the next 10 to 15 years will bring for video. Change is certain, and our company has shown time and time again that our customers have a partner who will keep them ahead of the curve.
