The project continued at Autodesk for four years, but no product was released.  van Dam's research groups at Brown University continued working as well. For example, in the late '70s Steve Feiner and others developed an ebook system for Navy repair manuals, and in the early '80s Norm Meyrowitz and a large team at Brown's Institute for Research in Information and Scholarship built Intermedia (mentioned above), which was heavily used in humanities and literary computing. In '89 van Dam's helped Lou Reynolds and van Dam's former students Steven DeRose and Jeff Vogel spun off Electronic Book Technologies, whose SGML-based hypertext system DynaText was widely used for large online publishing and e-book projects, such as online documentation for Sun, SGI, HP, Novell, and DEC, as well as aerospace, transport, publishing, and other applications. Brown's Center For Digital Scholarship (née Scholarly Technology Group) was heavily involved in related standards efforts such as the Text Encoding Initiative, Open eBook and XML, as well as enabling a wide variety of humanities hypertext projects. In the late 1980s, Berners-Lee, then a scientist at CERN, invented the World Wide Web to meet the demand for simple and immediate information-sharing among physicists working at CERN and different universities or institutes all over the world. In 1992, Lynx was born as an early Internet web browser. Its ability to provide hypertext links within documents that could reach into documents anywhere on the Internet began the creation of the Web on the Internet. Early in 1993, the National Center for Supercomputing Applications (NCSA) at the University of Illinois released the first version of their Mosaic web browser to supplement the two existing web browsers: one that ran only on NeXTSTEP and one that was only minimally user-friendly. Because it could display and link graphics as well as text, Mosaic quickly became the replacement for Lynx. Mosaic ran in the X Window System environment, which was then popular in the research community, and offered usable window-based interactions. It allowed images as well as text to anchor hypertext links. It also incorporated other protocols intended to coordinate information across the Internet, such as Gopher. After the release of web browsers for both the PC and Macintosh environments, traffic on the World Wide Web quickly exploded from only 500 known web servers in 1993 to over 10,000 in 1994. Thus, all earlier hypertext systems were overshadowed by the success of the Web, even though it originally lacked many features of those earlier systems, such as an easy way to edit what you were reading, typed links, backlinks, transclusion, and source tracking.
