Why Blogspot Dashboard appear Adsense?

Already long blog in blogspot not open .. being busy with wordpress, posting a fad and when the article in publishing. there is an overall look that appears a bit strange seen as a google adsense ads we put the blog.
blogspot but do have google, and so far never appeared ads on blogspot .. dashboard?

There were two allegations against these events:
There may be a bug in the dashboard post after publishing an article in "Your blog post published successfully!". blogspot and google adsense because they are interrelated with each other in the coding
Google needs the funds to maintain and Improve blogspot server, because the need for bandwidth, storage and a large number of blogspot users who are increasingly added many .... But do not be surprised this was the same as gmail, let us consider the email load time .. ! there must be some ad time we check email right?
But whatever the reason ... it saw course, wrote his name free blog, so the users participate wrote whatever they give is not it! just enjoy
