Just so no one forgets a few elements of the history of the WWW, often referred to as the World Wide Web.
1) In reality there was a beginning to WWW before HTTP servers appeared on the internet.
and only later did HTTP, or Hyper Text Transfer Protocol appear, along with HTML, or Hyper Text Markup language, a derived, or DTD from SGML (Standard Generalized Markup Language)
2) The original ‘Web’ browser was Mosaic as it place all of the WWW protocols under one browser. And linked these together to what we now call the World Wide Web, a real “Mosaic” of the Internet protocols.
I know this as I was developing Gopher and Anonymous FTP servers when HTTP was developed. And you can still find some of the protocols still listed in the URL of your favorite browser
