Yahoo and Adobe unveiled a  plan today to serve contextual ads within PDF files — one of the last bastions of (mostly) ad-free space on the internet.

Yahoo and Adobe will partner to allow publishers to run dynamically generated ads on PDF files posted on the Web or distributed via e-mail, opening up a new frontier in online advertising.

Until now, publishers have been able to embed only static ads on PDF files, but Yahoo and Adobe are developing a system to make those documents display contextually relevant ads delivered on the fly from Yahoo’s inventory at any given time.

The inclusion of pay-per-click text ads on PDF (Portable Document Format) files will give publishers another revenue-generating option for the content they have in this popular Adobe document format, said Kurt Garbe, entrepreneur in residence for advertising at Adobe.

This technology will probably be beneficial for the two companies as well as the advertisers. But how will it affect us, the common users? Will it add any new dimention to our web experience? Will it benefit us? What do you think?
