As of April 18, 2012 Google will be shutting down AdSense for domains. This only applies for domains hosted by Google. It means that you will no longer be able to generate money from your undeveloped domain. While AdSense was based on quality content, many domains that opted for Adsense had no content whatsoever. This led to great dissatisfaction amongst advertisers, thus resulting in Google pulling the plug on this service.
