## Definition
**Broadcast News corpora contain transcribed radio and television news material prepared for speech and language research.** They provide edited and semi-scripted journalistic language, named entities, public-affairs vocabulary and topic continuity distinct from casual conversation.
## Living Language Context
The source name `!bn_t.txt` and the political and journalistic texture of surviving trigger pairs suggest Broadcast News-derived trigger data in [[wiki/Living Language — Proximal Frequency Research Reference|Living Language — Proximal Frequency Research Reference]]. The interpretation is consistent with the material but remains a reconstruction until original documentation surfaces.
Used beside [[wiki/Switchboard Corpus|Switchboard]], broadcast transcripts provide a contrasting linguistic environment: public, topical and institutional language alongside spontaneous conversation. Differences between those corpora affect which associations appear important.
## Key Insight
**A corpus does not merely supply more words. Its social setting changes the conceptual neighborhoods recovered from it.**
