Google announced the support for a new AdSense ad unit, the size is super wide at 970×90.

I cannot even show you a sample of this ad because this site wouldn’t support it properly – it is so wide.

Here is a picture, you can click on it to see the true size.

Google said that if you use it, expect to see multiple text ads fill the spot or display ads being centered in the spot, until more advertisers design ad creatives that fit the 970×90 specs.

Google wrote on Google+:

The trend has been that Google AdSense ads have been getting larger and larger.
