HTML5 video
Support for HTML5 video has been steadily increasing. In June 2013, Netflix added support for HTML5 video. In January 2015, YouTube switched to using HTML5 video instead of Flash by default. In December 2015, Facebook switched from Flash to HTML5 for all video content.
Streaming media
Around 2002, the interest in a single, unified, streaming format and the widespread adoption of Adobe Flash prompted the development of a video streaming format through Flash, which was the format used in Flash-based players on many popular video hosting sites, such as YouTube, now defaulting to HTML5 video. Increasing consumer demand for live streaming has prompted YouTube to implement a new live streaming service to users. Presently the company also offers a (secured) link returning the available connection speed of the user.
