According to Murphy, the initial acronym was '''''Tape Editor and Corrector''''' because "[[Paper tape|punched paper tape]] was the only medium for the storage of program source on our PDP-1. There was no hard disk, floppy disk, magnetic tape (magtape), or network."<ref name=AnecD/> By the time TECO was made available for general use, the name had become "Text Editor and Corrector",<ref name=PDP8/> since even the PDP-1 version
by then supported other media.<ref name=AnecD/> It was subsequently modified by many other people<ref>{{cite web  |title=TECO  |work=The Jargon File  |version=v.4.4.7
