Detect if Google Analytics and Developer Media are loaded properly or not

This is for my own future reference. I need a way to check if Digital Media and Google Analytics JavaScript objects are loaded properly. There are browser's extensions such as Ghostery and Disconnect that will interfere or surrogate JavaScript objects and nullify the analytics behind the ads.

Here you go!

 <script type="text/javascript">
 window.addEventListener('load', function()
 {

 if(typeof DMAds==='undefined')
 {
 console.log('Developer Media is not loaded');
 }
 else
 {
 console.log('Developer Media is loaded');
 }

 if(window._gaq && (typeof window._gaq.I!== 'undefined'))
 {
 console.log('Classic Google Analytics is loaded');
 }
 else
 {
 console.log('Classic Google Analytics is not loaded');
 }

 console.log(window._gaq.I.prefix);
 }, false);
 </script> 

If the browser viewing the page with above JavaScript codes equips with Ghostery or Disconnect. You will see Developer Media is not loaded and Classic Google Analytics is not loaded under your browser's Console tab.
