What does dissemination mean? Dissemination is the act or process of disseminating—distributing, spreading, broadcasting, or dispersing widely. The word is especially used in reference to the distribution of information, or things that contain information, like files and documents. It is also associated with the official release of such information by organizations, such as the dissemination of a press release by a company or the dissemination of information to the public by a government agency. Example: Our chief media officer is responsible for the dissemination of press releases to various outlets.

Etymology
Origin of dissemination
First recorded in 1630–50; disseminat(e) ( def. ) + -ion ( def. )
Explanation
Dissemination is the scattering of information. If you've done something really embarrassing and don't want the whole school to know, let's hope no one who saw you is an expert in the rapid dissemination of humiliating facts. Dissemination builds on the word, seminate, meaning "to plan seeds." When you add the prefix dis-, you add the idea of separation, so to disseminate means to spread seeds widely. These could be literal seeds, like the dissemination of Oak genes by the scattering of acorns, or metaphorical seeds of ideas, like the dissemination of radical ideas through blogs, zines, and list-servs.
