Since 1985, the field of professional communication has grown in size and reputation while maintaining a space within its primary disciplinary home of the English department. This article relies on historical evidence to examine how a field that was once evenly divided between business communication and technical communication is now technical communication-centric, almost to the exclusion of business communication. The authors pose questions about the field of professional communication and how faculty who consider business communication to be their primary discipline (regardless of their disciplinary home) might play a role in future discussions related to disciplinarity and domains of knowledge.

自 1985 年以来，专业交流领域的规模和声誉不断增长，同时在英语系的主要学科范围内保持着一定的空间。本文依靠历史证据来检验一个曾经平均划分为商务传播和技术传播的领域，现在如何以技术传播为中心，几乎将商务传播排除在外。作者提出了有关专业传播领域的问题，以及将商务传播视为其主要学科（无论其学科所在）的教师如何在未来与学科和知识领域相关的讨论中发挥作用。
