Our WebM Microsoft Media Foundation components enable WebM playback support in Internet Explorer, beginning with IE9 on Windows Vista. They should also work on newer versions of IE and Windows.

Once installed, the WebM components will automatically check for updates and install them.
Microsoft does not ship IE with WebM codecs built in, so the codecs must be installed in Windows separately. We worked closely with Microsoft to integrate WebM with IE, to help provide a great HTML5 user experience for Windows users. For more background, see Internet Explorer General Manager Dean Hachamovitch's blog post on the subject.
WebM was built for the web. By testing hundreds of thousands of videos with widely varying characteristics, we found that the VP8 video codec delivers high-quality video while efficiently adapting to varying processing and bandwidth conditions across a broad range of devices. Also, the relative simplicity of VP8 (the video codec in WebM) makes it easy to integrate into existing environments and requires comparatively little manual tuning in the encoder to produce high-quality results.
YouTube is supporting WebM in addition to its existing formats as part of its HTML5 experiment. For instructions, see our Users page.
No. Older versions of IE do not support HTML5 video functionality.

The components are installed directly in Windows, not Internet Explorer. They are system-level software libraries built using Microsoft Media Foundation, a digital media platform in Windows Vista (and up). Because the components are installed in Windows, the components can render WebM in other applications that support MF, such as Windows Media Player.
Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
