Ads customization

In these sites they customized the ad display...

I see that google only supports these formats mentioned in their site.
[google.com...]

They say we have to cut and paste the code as it is... should not change it...
[google.com...]

But at these sites I found it has been customized / altered, got different code.
[4guysfromrolla.com...]
[sifymax.com...]

How come? can we get the code like that & the different header like "Sponsored Links" instead of "Ads by Google"?

Any idea?

First of all, you should remove the links due to TOS. And one of those sites is en established publisher and am currently a premium adsense partner.

Premium AdSense service available if your site receives 5 million+ search queries or 20 million+ content page views a month.

So customization is enabled for them.
