Found Weird Custom Adsense Code on another Site?

I found this site http://www.autoevolution.com/news/infiniti-ex30d-gt-photos-and-details-17417.html
and i really liked the way their adsense is set up....so I was looking at the source code and saw this weird piece of code....

<!-- custom adsense start -->
<script type="text/javascript">
function google_ad_request_done(google_ads)
{
if (google_ads.length > 0)
{
if(google_ads.length == 1){ cls1 = "celltext_bigad"; cls2="celltext_bigad"; height = "height=570"; padding = "<br/><br/><br/><br/><br/><br/>"; }
else{ height = ""; padding = ""; cls1 = "celltext_big"; cls2 = "celltext"; }

var adcode = '<h1 style="font-size: 120%;"><a rel="nofollow" href="'+google_info.feedback_url+'">Ads by Google</a></h1>';

var ex_style = '';
var margin_up = 10;
if(google_ads.length == 1){ ex_style = 'font-size: 150%;'; margin_up = 85; }

for(var i = 0; i < google_ads.length; ++i)
{
if (i < 6)
{
adcode += '<div style="width: 140px; margin: '+margin_up+'px 0 15px 10px; overflow: hidden; font-size: 110%; '+ex_style+'">'+
'<a onmouseover="window.status=\'' + google_ads.visible_url + '\'; return true;" onmouseout="window.status=\'\'; return true;" href="' + google_ads.url + '"><b style="font-size:120%;color:#000000;">' + google_ads.line1 + '</b></a>' +
'<br/>' + google_ads.line2+ ' ' + google_ads.line3 + '<br/>' +
'<a onmouseover="window.status=\'' + google_ads.visible_url + '\'; return true;" onmouseout="window.status=\'\'; return true;" href="' + google_ads.url + '"><font color="#444444">'+google_ads.visible_url+'</font></a>'+padding+
'</div>\n\n';
}
}
}
else
{
adcode = '';
}

if(document.getElementById("first_ad_unit")) document.getElementById("first_ad_unit").innerHTML += adcode;// + '<div class="leftcolsep" style="margin-left: 10px;">&nbsp;</div>';
}

google_ad_client = "pub-2364887827571271";
google_hints = "auto, moto, truck, automotive, F1, WRC, BMW, Chevrolet, Peugeot, Ford, Volkswagen, Mercedes, Audi, Fiat, Honda, Volvo, Vauxhall, Toyota, Renault, logbook";
google_ad_output = 'js';
google_max_num_ads = '6';
google_feedback = "on";
google_ad_type = "text";
google_color_line = "ff0000";
//google_ad_channel = "1368523270";
google_ad_channel = "0278960851";
</script>
<script type="text/javascript" language="JavaScript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script>
<!-- custom adsense end -->

what the heck is it and what the heck are Google hints and how do I use this on a wordpress blog?

 

Premium Publisher, I suspect...thus they can do what they do, but don't do it yourself if you don't have permission.

 

That site has a homepage PR of 6. They get traffic and Google recognizes this.

Google has different programs for different vendor levels and areas of expertise.

 

I guess It's premium publisher.If You have a very good website then You can ask for premium publisher.

 

Never knew there was such a thing as a premium publisher.

 

How does one qualify as a premium publisher?

 

All you need is at least 20 million page views per month and a special invitation from Google.
