I was still messing around with IE6 as late as 2012...the web agency I worked at had clients in huge old school companies who must have had proprietary internal software that depended on it. Whenever we thought we could finally ditch it, we'd get forwarded an email from a higher up at a client company with a subject like "??????" containing a screenshot of our pre-launch environment for a new site looking entirely broken in IE6. At that point we had this giant wad (like, several files and multiple megabytes?) of JS and CSS of uncertain provenance that we'd conditionally load for IE6 that magically made almost all of the more modern stuff actually just work. I'll never forget the feeling of rage-then-relief when the screenshot situation above happened a matter of hours before a major site launch. I booted my IE6 VM, shrieked at how utterly broken the site was, copied over that ungodly blob of polyfills and dark magic, reloaded the page and everything looked correct. I was working in a coffee shop and may have whooped out loud.
