This only holds true for publications with a very specific audience though and even then, it's not going to be optimal. Of course if you have a purely tech oriented blog, or even better, one focused on a specific technology, then surely you can get decent results by partnering with one specific advertiser specific to that niche, but as soon as your audience gets more diverse, like the audience of your average run of the mill newspaper would be, you will be loosing out on a ton of ad revenue if you don't try to target your ads. So while this is a cute idea, I doubt it is practical for any publication of noteworthy size.
