I work for a certain big studio and I still see fax machines, all stand-alones. The “fax” feature is mostly part of multi-function printers like HP, Minolta etc. and it’s not going away. I know old-school producers who would “fax” script changes (not send by email etc) and we would wait for it while eating lunch.
Yeah, I know. I have fax capability on my printer/scanner/copier/fax machine.
