"quite some time", is an understatement. The Apache HTTP Server was included as part of Mac OS X starting with version 10.0 (Cheetah), which was released on March 24, 2001. Prior to that, users of Mac OS X would have to manually install and configure Apache HTTP Server, if they desired to run a web server on their Mac.

Was there a meaningful "before" for Mac OS X? 10.0 was the first X (unless you mean developer previews and the like).

Mac OS X server had 1.0, 1.1 and 1.23 released before 10.0 was released, based on Rhapsody.

Apache was one of the installable options alongside Emacs and WebObjects.
