Adobe Reader 8 Vs. 9
Adobe Reader, originally known as Adobe Acrobat Reader, is Adobe's proprietary software for reading their Portable Document Format (PDF). Adobe Reader can only read PDF files, while the Adobe Acrobat Professional edition is needed to edit and create PDFs with full functionality. Adobe released the PDF and accompanying Acrobat software during the beginning of the 90s, amidst much competition. PDF and the accompanying Adobe Reader are now the de facto standard for document formats.

Version 8 Vs. Version 9
-
The differences between version 8 and 9 of the Adobe Reader are very minor compared to the differences between the authoring-backend Adobe Acrobat Professional software. Adobe Reader 9, while including natural bug fixes associated with new software versions, also mimics its parent Acrobat Professional software and includes better Flash support. If you need a PDF reader with better and more integrated Flash support, then upgrade to version 9, but otherwise the differences are slight, with both versions effectively operating in the same way.
