Strange New AdSense Format

I ran across a brand new AdSense format this morning on Plenty of Tee Times:

Now I would have argued that this was some other contextual ad unit, not AdSense, but it definitely is. Take a look at the code behind it. It’s your standard 728×90 ad unit, but it’s very different than any version that I’ve ever seen.

Anyone else seen this? I checked JenSense this morning, but she hasn’t mentioned it yet.

Update:
Leave it to Jen. I knew she’d know the answer:

That actually isn’t a new ad format, that is the AdSense ad unit that will appear if a publisher has screwed up the ad javascript - if you look in the source, the publisher went and put the entire ad unit javascript into a single line which can cause that type of ad unit to appear. It can also appear when you just include the second part of the javascript on a page when you have already included the entire javascript elsewhere on a page.
So nothing new, just the publisher got it wrong when adding the javascript to a website… and now that it’s gone public, he very likely will be getting a warning from Google, because this time of thing has been posted on DigitalPoint, and the webmaster then got a warning from Google about not pasting the javascript exactly how it appears in the control panel.

There you have it: screw up your AdSense code, and Google shows that odd format so that it’s easier to see that it’s wrong.

Thanks, Jen!
