tech2.com can be a premium publisher to put like that, you have another option putting a banner (468x60) ad block, it will not display the advertiser URL..
Yes Google offers customized ads for Premium Publishers who receive more than 5,000,00 impressions a month. You can hide the advertiser url using 468 X 60 banner.
You can disable this option in in the adsense Control Panel "My account" This is the option above your adsense ID in the bottom
For lesser mortals we can "hide" (not removed) the URLs by using: google_color_url = "FFFFFF"; for white background (or the color of the background).
Both 330td and ainmohd are wrong, there is no option to disable other than I replied above and even if you make #FFFFFF still it will show in light grey color..
mint, its not 5,000,00 impressions a month, its 20 million. tech2 is part of TV18 network and a premium publisher. Those ads are damn nicely blended. I already discussed this in March 2007.
I still dont got the answers guys, how to hide the links. i seen more such ads with no links. Is this resticted to only premium publishers?
