Samuel Smith ported the algorithms of Phil Katz's original "PKZip" program, into an open source project he called "Info-ZIP", way back in 1989 (Katz had published how they worked, anyway).
He released it under a BSD license, so essentially everyone else's "Rocket-Powered ZIP program", ever since, has been (pretty much) a cut&paste job, as far as the actual archiving process goes. (Many such defacto standards are the product of a BSD licenses meeting up with the ctl-c and ctl-v keys. How do you think we ended up with TCP/IP?)
("What's that, you say, Skippy? 'Attribution'? Oh, there's a comment in the source code - honest!")
