> In the 1990s we saw the mass industrialization of web development with PHP and Apache HTTP Server.

This isn't really true. PHP4 wasn't released until 2000. Sure, OK, while there were people using PHP3 in the 90s, it wasn't nearly as ubiquitous to the point of "mass industrialization". PHP3 wasn't even much of a language to begin with and if anything, Java/J2EE was the stack used for "mass industrialization" (Java's role is still dominant in most domains today). Perl was also a much more popular scripting language at the time.
