== 1990 to 1999: Prominence of the Internet ==
The rise of the [[Internet]] led to very rapid growth in the demand for international information display/e-mail systems on the World Wide Web.  Programmers were required to handle illustrations, maps, photographs, and other images, plus simple animation, at a rate never before seen, with few well-known methods to optimize image display/storage (such as the use of thumbnail images).{{citation needed|date=February 2016}}

The growth of browser usage, running on the [[HyperText Markup Language]] (HTML), changed the way in which information-display and retrieval was organized.  The widespread network connections led to the growth and prevention of international [[computer virus]]es on MS Windows computers, and the vast proliferation of spam e-mail became a major design issue in e-mail systems, flooding communication channels and requiring semi-automated pre-screening. Keyword-search systems evolved into web-based [[search engine]]s, and many software systems had to be re-designed, for international searching, depending on [[search engine optimization]] (SEO) .  Human natural-language translation systems were needed to attempt to translate the information flow in multiple foreign languages, with many software systems being designed for multi-language usage, based on design concepts from human translators.  Typical computer-user bases went from hundreds, or thousands of users, to, often, many-millions of international users.{{citation needed|date=February 2016}}
