NNTP makes distributed discussion a protocol
NNTP defined a common way to retrieve, post, and distribute network news articles.

Context and provenance
RFC 977, published in February 1986, specified the Network News Transfer Protocol. It described how programs could exchange news articles, select newsgroups, and retrieve individual messages through a shared set of commands and responses. A discussion did not need to exist only inside one company's application; servers and reading software could cooperate through a documented protocol. Message identifiers and article references helped connect items across that distributed environment. NNTP did not invent all online discussion or all Usenet practices. Its contribution was to give network news a concrete communication mechanism that could be implemented by different systems and later revised through new specifications.
Why it matters
Editorial perspective: A conversation can be organized as shared infrastructure rather than a destination owned by one interface. That distinction changes portability and continuity, even though it does not automatically solve moderation, trust, or discoverability.
