Organic Results in Google's Right Hand Column?

Today I saw a story on Sphinn from Search Engine Roundtable about Google serving up video ads in search results. Don't worry, I'm not out to rehash this development for the 50th time today... I saw something similar last week -organic video- in the sponsored links column!!! Notice that they aren't ads at all, but youtube videos and some Google book results.

If I had to guess, I'd say Google is experimenting with the effective use of dead space to keep it in people's reading zone. "Tomorrow" isn't really worth bidding on so there is always free real estate on the right hand side that might as well be filled in with relevant content.

I'm really curious to see if organic video will be mixed with Adwords text and video ads. Would it decrease revenue by blocking out spaces on the front page, or encourage more people to look to the right hand column for relevant results?
