A new advertising channel is coming to town with Yahoo and Adobe teaming up to provide dynamically generated (and, hopefully, relevant) ads on PDFs (Portable Document Format) either via the Internet or email. I think this news is welcome if you are into producing documents and looking for new ways to monetize your efforts (pay-per-click model). My concern for Adobe is that, given the current size and speed of Reader, people would opt for more agile readers such as Foxit which would eventually catch up.
