In a move meant to decrease the number of accidental clicks, Google has reduced the clickable area of the AdSense ads to the title of the ad and its URL below.

This will result in a decreased CTR for all webmasters, but especially those who earned money from accidental clicks, and hopefully an increased overall revenue per click, thus rather good news for web developers who did not register a significant number of accidental clicks.
