Here is another fun fact: The convincing UI of ed was actually so widely 
applied, that even Microsoft included a similar editor into MSDOS, 
called EDLIN. EDLIN, of course, was a bastardized version of ed that 
could do much less and also lacked regular expressions. Needless to say 
that the mighty "VIsual" editor was out 5 years before MSDOS shipped 
EDLIN as the only editor...

In contrast to ed, the stream editor "sed" is used multiple times avery 
day in a typical Unix session inside shell scripts to perform automated 
text processing tasks, including regex replacement.
