HTML is the standard, set by [[w3c]], for how to write webpages. HTML5 was supposed to include a standard way to add video to webpages, but after lengthy discussions about [[software patents]], the drafters announced on June 30th 2009<ref>http://lwn.net/Articles/340132/</ref> that they could find no freely implementable video format to recommend.
 
 
 
The two main candidate formats were [[H.264]] and [[Ogg Theora]], but the former is heavily encumbered by patents while the latter's future was deemed questionable because, as [[Google]]'s Chris DiBona said:
 
<blockquote>
 
''Here’s the challenge: Can [T]heora move forward without infringing on the other video compression patents?''<ref>http://www.mail-archive.com/whatwg@lists.whatwg.org/msg15476.html</ref>
 
</blockquote>
 
 
 
A third option discussed was to [[use software from 20 years ago]]: MPEG-1.
 
 
 
HTML is an open [[harm to standards|standard]] and aims to be patent-free.  Consequently, the risk of patent encumbrances is posing a real problem in extending HTML to provide a standard video interface.
 
 
 
[[Microsoft]] announced in April 2010 that they will only support the heavily patented Mpeg [[H.264]] for the HTML5 video tag.<ref>http://blogs.msdn.com/ie/archive/2010/04/29/html5-video.aspx</ref>
 
 
 
==Other software patent issues for HTML5==
 
 
 
In 2007, [[Apple]] claim to have patents covering the "canvas" tag,<ref>http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2007-March/010129.html</ref> but they later solved this problem by agreeing to license those patent(s) under the [[w3c]]'s royalty-free terms.<ref>http://www.w3.org/2004/01/pp-impl/40318/status#current-disclosures</ref>
