Update: NewTeeVee reports that Netflix will not be using HTML 5 for video. Adrian Cockcroft explains that DRM is the reason they can't switch to HTML 5 video yet:
“I was thinking of HTML5 features that let us build very cool user interfaces with drag-and-drop, canvas transforms etc. for the web site, and for embedded TV devices specifically. The Silverlight player is used for PC/Mac playback only, and the basic HTML5 Video doesn’t have a viable DRM solution at this point."
It looks like Netflix is the latest company moving to HTML 5, according to a blog post by Adrian Cockcroft, Netflix's Cloud Architect:
Come to Netflix where we are using HTML5 based web technologies to move ecommerce directly onto televisions in our customers’ living rooms. As of our Customer Acquisition team, you will lead the way to our internationalized television user interface designed to help new customers find Netflix and start streaming movies in seconds. This new experience will be deployed to HTML5 capable embedded browsers and served from our cutting edge cloud based backend service.
Cockcroft did not make it clear if Netflix would move the HTML 5 on the desktop, but does note that HTML 5 is "...now supported by a large and rapidly growing percentage of the visitors to netflix.com."
One of the fun things about working at Netflix is that we are always "leaning forward" and looking for new technologies to leverage. As we roll out our website to run on the Amazon cloud, we are also re-architecting the code base, adding internationalization support and bringing in the latest technologies. One of these is HTML5, which is raising the bar for cross browser support for advanced user interface features, and is now supported by a large and rapidly growing percentage of the visitors to netflix.com. In addition many TV based devices now embed webkit, which is the HTML5 compatible technology that underpins the Safari and Chrome browsers.
