Not to be pedantic but Limewire wasn't released in the 90's, 1999 on the title is at least close to a good date but 1990 is way to early for programs like Limewire, that's basically Universities and Military only internet times.
Took a quick look at the wiki and have to admit that this is hilarious:
Both a zero-cost version and a purchasable "enhanced" version called LimeWire Pro were available; however, LimeWire Pro could be acquired for free through the standard LimeWire software, where users distributed it without authorization.
