The .nzb extension is bound up with the NewzBin Usenet Index File (NZB) file type/format. NZB is a plaintext XML-based format for defining pointers to Usenet posts. Usenet is an old BBS-like server-based message exchange network with a hierarchy of topical channels (newsgroups), similar to today's Internet forums but greatly outdating them.
NZB was introduced by NewzBin, a Usenet indexing site with a controversial reputation for hosting pirated materials. Even before the complete shutdown of NewzBin in 2012, NZB was picked up as a de facto standard Usenet index format by many similar indexing sites and services.
Any .nzb file is a small XML text file, acting as a pointer to a Usenet post, and usable with any Usenet client. The .nzb file type is typically associated with various Usenet clients, depending on OS/platform.
Aside from the discontinued NewzBin, there are many other sites/services that offer indexes of various content found on the Usenet and can generate .nzb pointers for any user-selected posts, without the need to update channel headers on the client side. The use of .nzb pointers is especially advantageous with binary data.
