People would refer to "The Software Development Life Cycle", which was by all means a waterfall-esque process (look it up on Google, you'll see the classic waterfall diagram used for it). The word itsself may have been coined as something to compare Agile against, but the process itself existed, and existed long after Agile had "won" in more traditional companies. I ran projects that ran through a VERY traditional waterfall process as recently as 2010.
