Well, the initial discussion was archival programs, zip vs. tar. Zip
also compresses the archive, which is very beneficial but is not
necessary to the archival process.
I counter the gzip quote with compress, which was the predecessor of
gzip. Compress predates PKzip (January 1989), albeit tar & compress is
a two step process instead of a one step process. (The primary reason
gzip was created was to avoid the "submarine" patent that torpedoed
<http://en.wikipedia.org/wiki/Compress> "The LZW algorithm that compress
is based on was being patented by Sperry Research Center in 1983. The
person who applied for the patent published an IEEE article on the
algorithm in 1984, without mentioning that the algorithm was patent
pending. Spencer Thomas took this article and implemented compress in
1984, without realizing that the LZW algorithm was patent pending."
