Video startup JW Player has raised a fresh $20 million round of funding to grow beyond its status as one of the most used non-YouTube video players. It’s a SaaS video platform, and it powers one of the largest open-source video players available, so the chances are pretty good that nearly everyone surfing the web has used it at least once before. The company claims that about five percent of all video streamed happens through its JW Player across 2 million sites to 900 million monthly unique viewers. JW Player is significant because it’s a solution for video publishers who find they can’t generate enough revenue through YouTube alone.
