JAMA celebrated its 140-year anniversary in 2023. In reflecting on JAMA's origins and the descriptions of why JAMA was created, 1 one immediately recognizes the founding principles that still inform our priorities today. The earliest references to the creation of JAMA declare 1 : "But we shall spare neither time nor labor to complete such arrangements as will make the JOURNAL an efficient representative of the scientific, social, and ethical interests…," a sentiment that resonates with our current approach at JAMA.In this year-in-review editorial, we report on key metrics for JAMA. Based on the 2023 numbers (Table ), 2-6 JAMA continues to be a global leader in publishing quality clinical research, reviews, and opinion; having high impact, influence, and reach; and using multiple modes of publication. Here we focus on JAMA authors and readers whose work and interests are represented by these metrics, and the new initiatives launched at JAMA to serve authors, readers, and the broader medical and scientific communities.
