You know the double-underlined words that you see while you're reading through content? That's contextual advertising, mostly a CPC model, based on relevant keywords within content. Nothing new there.
However, one of the biggest contextual advertising networks out there has just bought Image Space Media , adding an interesting layer to contextual advertising and expanding their offering. The same contextual technology will be applied to images within publishers' sites, taking advantage of the "30% of publishers' content" which is images. The deal will drive a combination of ISM's image technology with Vibrant's massive scale and will certainly play a role in pushing out ho-hum online advertising in 2012.
