That's an excellent observation. IIRC, back in 1996 there were still radio ads along the lines of "And available online at w-w-w-dot-c-n-n-dot-com or AOL keyword CNN" (or, worse yet, some that added h-t-t-p-colon-slash-slash-w-w-w-dot...).

I'll try to avoid stewing on the fact the CEO where I work is very hands-on with our website, despite never using the web. It's 2017 and he has every button replaced with beveled images of buttons...

EDIT: to reconcile "very hands-on with our website" and "never uses the web", I should specify that he orders changes to the website via the following process: 1) has someone print out the website 2) that gets faxed to him 3) he writes on it with a sharpie 4) that gets faxed back 5) that fax gets scanned 6) resulting scan gets emailed to the web design guy.
