Google Adsense recently announced that Adsense publishers now have an additional ad format to use in their sites: the 200×200 Small Square ad.
The new format is smaller compared to the original Square (250×250) format, hence, the name "Small Square." Like the Square format, the Small Square also supports text, image, and video ads.
You can see the Small Square ad in action here in PMT on the top-right side of all full-page articles.
