&gt; This is a false comparison. Logos for clothes sit on the clothes which are themselves judged entirely on their appearance.<p>Some do.  The vast majority of designer clothes don&#x27;t.<p>People buy the brand, not the product.<p>&gt; Google&#x27;s search engine has a separate function that stands on it&#x27;s own two feet irrespective of a change to an &#x27;e&#x27;.<p>People bought into the Google brand identity.  They were the first to eliminate all the crap around their web search engine, so it would just be a single text box.  This made sure people know what Google was - the simple search interface.  All of this is part of the brand&#x27;s visual identity.<p>Do you think they do an empirical study on this when they first made it?<p>It is your brand that sells your product.<p>The shape of the letter &#x27;e&#x27; is part of that marketing that sells your product.<p>In fact, EVERYTHING you do is fundamentally related to sales.  You are always closing.
