This essay is an introduction to the special issue on “Rethinking and Expanding Communication Theories on HCR’s 50th Anniversary.” We begin by arguing that communication research has expanded substantially since Human Communication Research’s inaugural issue. However, in light of changes in communication technologies, political discourse, means of engaging in interpersonal communication, and awareness of the importance of diversity and inclusion, this special issue takes note of our current theorizing and ways to build as we look toward the future. The essays in this special issue, reviewed in this article, will undoubtedly prompt us to re-think, re-envision, and renew our commitment to the importance of communication theory, both in terms of where we have been and in terms of where we can progress.
