This nationwide study of 169 business communication instructors examines the following issues: (a) ideal and actual class sizes in business communication courses, (b) delivery modes of business communication courses, (c) types of written and oral assignments, and (d) topics covered and depth of coverage. Findings suggest that business communication course offerings are growing on the national stage. The vast majority of class sizes have stayed the same or gotten smaller. One significant change over the past 5 years is the increased focus on interpersonal communication and teamwork. While some courses offer significant coverage of social media, the majority does not.
