From SEOMOZ about google updates timeline
Page Layout #2 — October 9, 2012
Google announced an update to its original page layout algorithm change back in January, which targeted pages with too many ads above the fold. It's unclear whether this was an algorithm change or a Panda-style data refresh.
If we apply these rules to google.com itself then may be they wont appear in their own SERP after today's changes. :)
