This article reflects my observations about major changes in organizational behavior (OB) during my 50 years working in the field. I begin with a brief description of my personal journey as foundational for my perspective. I then discuss how the field has changed structurally and focus on the contributions of the Academy of Management (AoM) and the increasing diversity of our members, especially the increasing number of women, minorities, and people from countries other than the United States. The next section covers major research content changes in the field including positive scholarship, leadership, affective constructs, ethics, and the general well-being of those who toil in the organizational trenches. Additionally, there is a section on how the utilization of new statistical procedures and research methods has greatly expanded our ability to investigate and test complex theories and hypotheses about behavior in organizations. The discussion section highlights both the positive aspects of these developments along with some concerns about the future.
