Unrelated: During the dot-com boom, there was a company called nCompass Labs that developed one of the first content management systems (https://en.wikipedia.org/wiki/NCompass_Labs_Inc). Microsoft bought them in 2001. Their product was, "a plug-in for hosting ActiveX controls in Netscape Navigator named ScriptActive." ActiveX itself was a novelty, using C++ templates to define reusable and _downloadable_ web components.

All of this crap was happily replaced with JavaScript frameworks in later years. Yes, back in the early-2000s, your browser might literally download executable code just to render a custom button.
