I was just updating my adsense codes for a new site and the Adsense code as actually changed now! <script type="text/javascript"><!-- google_ad_client = "pub-xxxxxxxxxxxxxx"; //Insert Name Here google_ad_slot = "xxxxxxxxxx"; google_ad_width = 160; google_ad_height = 600; //--></script> <script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script> Code (markup): As you can see the code is smaller, no color data etc. It actually takes you to a new page now to get the code and it states it could take up to 10 minutes for the changes to take effect.
I think google seems using Adsense new feature "Manage Ads" code replaced previous We are not need to modify web page code for change adsense ads template
