Adobe cancels in-PDF advertising program

I'm not particularly shocked by the decision. First of all, I have to say, I didn't exactly run across many PDF files online that were making use of the technology. And second, it wasn't particularly hard to avoid the ads if you wanted to. So I can't imagine anyone was getting getting rich here.
Publishers will no longer be able to upload ad-enabled documents after January 16th, and ads embedded in existing documents will stop displaying after March 31st.
