<h1>Web Media API Snapshot - Support by Year</h1>
<p>This <em>non-normative</em> document attempts to visually capture which
APIs are specified in <b>Section 3. Web Media APIs currently supported
on all platforms</b> for each year the
<a href="https://github.com/w3c/webmediaapi">Web Media API Snapshot</a>
has been published. This should only be used as a guide and not a formal
reference. The annual snapshots themselves are the only formal, normative
reference.</p>

<ul>
<li>! = exception(s) exist</li>
<li>+ = note(s) exist</li>
<li>✓ = API is included</li>
<li>Number/Year = the version/level of that specification</li>
<li>Date = Review Draft date of a Living Standard (either that version or a later one should be used)</li>
<li><i>(via HTML)</i> = implicitly included due to the contents of the specification being folded into the HTML specification</li>
