It was for some time the server counterpart to NCSA Mosaic. It also introduced the Common Gateway Interface, allowing for the creation of dynamic websites.
After Robert McCool left NCSA in mid-1994, the development of NCSA HTTPd slowed greatly. An independent effort, the Apache project, took the codebase and continued; meanwhile, NCSA released one more version (1.5), then ceased development. In August 1995, NCSA HTTPd powered most of all web servers on the Internet;<ref name=":0">{{cite web|title = Web Server Survey {{!}} Netcraft|url = http://news.netcraft.com/survey/|website = news.netcraft.com|access-date = 2016-02-16}}</ref> nearly all of them quickly switched over to Apache. By April 1996, Apache passed NCSA HTTPd as the No. 1 server on the Internet, and retained that position until mid-to-late 2016.<ref name=":0" />
