Portable Document Format

The Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. In 1991, Adobe Systems' co-founder John Warnock outlined a system called "Camelot" that developed into PDF.

Adobe Systems made the PDF specification available free of charge in 1993. PDF was a proprietary format controlled by Adobe, until it was officially released as an open standard on July 1, 2008, and published by the International Organization for Standardization as ISO 32000-1:2008, at which time control of the specification passed to an ISO Committee of volunteer industry experts. In 2008, Adobe published a Public Patent License to ISO 32000-1 granting royalty-free rights for all patents owned by Adobe that are necessary to make, use, sell, and distribute PDF compliant implementations. However, there are still some proprietary technologies defined only by Adobe, such as Adobe XML Forms Architecture and JavaScript for Acrobat, which are referenced by ISO 32000-1 as normative and indispensable for the application of the ISO 32000-1 specification. These proprietary technologies are not standardized and their specification is published only on Adobe’s website. The ISO committee is actively standardizing many of these as part of ISO 32000-2.

Adobe Creative Cloud

Adobe Creative Cloud is a software as a service offering from Adobe Systems that gives users access to a collection of software developed by Adobe for graphic design, video editing, web development, photography, and cloud services. In Creative Cloud, a monthly or annual subscription service is delivered over the Internet. Software from Creative Cloud is downloaded from the Internet, installed directly on a local computer and used as long as the subscription remains valid. Online updates and multiple languages are included in the CC subscription. Creative Cloud is hosted on Amazon Web Services.

Previously, Adobe offered individual products as well as software suites containing several products (such as Adobe Creative Suite or Adobe eLearning Suite) with a perpetual software license.

Adobe first announced the Creative Cloud in October 2011. Another version of Adobe Creative Suite was released the following year. On May 6, 2013, Adobe announced that they would not release new versions of the Creative Suite and that future versions of its software would be available only through the Creative Cloud. The first new versions made only for the Creative Cloud were released on June 17, 2013.
