 From the Adobe Developer Connection website:

"The PDF specification was first published when Adobe Acrobat was 
introduced in 1993. Since then, updated versions of the PDF Reference 
have been made available from Adobe via the Web. A significant number of 
developers and systems integrators offer customized enhancements and 
extensions to Adobe's core family of products. Adobe publishes the PDF 
specification to foster the creation of an ecosystem around the PDF 
format. The PDF Reference provides a description of the Portable 
Document Format and is intended for application developers wishing to 
develop applications that create PDF files directly, as well as read or 
modify PDF document content."

(Note that this is why open source as well as non-Adobe commercial 
software can legally read and create, and even add goodies to, PDF 
files. To name a few: OpenOffice, PDFCreator, Mac OS X, ...)
