Monday 2nd June 2008, Adobe announces the release of
Adobe Acrobat 9.

The major highlights of this particular version is that Acrobat will have
integration of a wide variation of online content such as Adobe Flash, video, audio and 3D objects into one compressed PDF file. This feature is mostly beneficial to authors of e-books in distributing their online books with digital multimedia content... a much more organized method for authors to display multimedia content in their PDF documents for readers (in other words, everything is in one file) - without the fuss of having the reader lose focus from the document to search the content elsewhere.
The software also features
live collaboration in PDF documents through Adobe.com to establish communication to all readers using the free Adobe Reader software... I find this feature would prove most useful in remote learning establishments like remote learning university programs where the
author/lecturer can ensure all readers are on the same page in discussion during a live conference thats taking place.
