Originally, it was developed by the Sun, as the "small cousine" of the Java.
The "World Wide Web" was originally developed only for static content without client-side dynamical behaviors, and with only zero to little server-side dynamical content.
There were still some possibilities for dynamical content, mainly by server-side support, but its possibilities were very weak. For example, images could dynamically created and re-used by sending refreshing http headers with images, and then refer them in
<img src=... tags.
The most common technology before the WWW was gopher, which supported only static content, too. At this time, non-graphical user environments were more common, they were remotely used by telnet, or more early, by serial terminals.
