Why big corporations do not include the copyright notice into their WEB [HTML] code?
<p>One of the first things that I learned when writing code was to copyright it. As far as I know, the things to do are:</p>
<ol>
<li><p>Create a license file that describes the copyright and lists the
software files.</p>
</li>
<li><p>Add the copyright to each file containing code. Ex: <code># (C) Copyright &lt;years&gt; &lt;name&gt;. &lt;license&gt;.</code></p>
</li>
<li><p>[Optional] Register the software into official organizations of intellectual property.</p>
</li>
</ol>
<p>the stages 1) and 2) I've always seen it in heavy client software, but I ignore why big corporations like Facebook, Google, Microsoft, etc... never do it in their web code (speaking about step 2). And they also don't even use the HTML meta tags:</p>
<pre><code>&lt;meta name=&quot;author&quot; content=&quot;&quot;&gt;
&lt;meta name=&quot;copyright&quot; content=&quot;&quot;&gt;
</code></pre>
<p>Is there any legal reason behind this? Is their code already declared on step 3 so they don't bother doing step 2?</p>

<h2>One of the first things you learned was wrong</h2>
<p>Or, at least, incomplete.</p>
<p>Copyright exists the instant the literary or artistic work is &quot;fixed&quot;: that is, recorded in some manner that is retrievable and reproducible. Under the <a href="https://en.wikipedia.org/wiki/Berne_Convention" rel="nofollow noreferrer">Berne Convention</a>, a requirement in domestic law that a work is registered or marked with a copyright notice is not allowed.</p>
