Alright, we keep on seeing such things from Google Adsense. Few days back we had this Google box besides the ads, replacing the word Google in “Ads By Google” 
Now i see some more changes, and you know what, this is the coolest change. I really like it. No irritating, Ads By Google link on top of ads. Instead you see Ads By Google in bottom of an advertisement bopx and that too in a very stylish way.
Here is how it looks like
Well this certainly looks much better than the previous ads. However i do not see this on every advertisements out there. But do get a chance to see this once in a while. The Big G Adsense is experimenting with the ads for sure. Probably something better for us, in the future.
