And the excellent, classic book "The Pragmatic Programmer" promoted it 
as a technique worth having in one's toolbelt (That book, along with 
"Writing Solid Code", left a big lasting impact on me.)

IIRC, in the earlier days of Gameboy Advance homebrew (back when I still 
had time for that sort of thing!) it was also the first common technique 
for including images/audio in a ROM image. (Until other tools were 
developed to handle the task better.)
