The ```window.resize``` fires constantly as a user resizes the screen, therefore, this should be debounced to avoid DOM trashing.  Our new common convention is to use Lodash's method: http://lodash.com/docs#debounce

I.e.
```JavaScript
 mediator.on('window:resize', _debounce(function(), {
        Adverts.hideAds();
    }, 500);
});
 ```
