Anniversaries often focus our minds on the past, serving as an opportunity to bring people together to reflect upon a shared and storied history. The fiftieth anniversary of Environment and Planning B (EPB) is no different in this respect-with so many current, former (and probable future!) editors offering their perspective on our journal, we are fascinated by how this shared intellectual project has inspired such a diversity of perspective, opinion, and experience. Many reflections on the journal focus on a few core pivot points, such as the changing of subtitles (1974( , 1979( , 1982( , and then most recently again in 2017( , as Batty (2024 outlines in this issue). This makes sense, as changing a title changes both how a journal "frames" its intellectual work, but also changes how others in the world see that journal. In particular, the most recent revision, from Planning and Design to Urban Analytics and City Science, is a significant transformation in many of our contributors' perceptions of what EPB is and, critically, what we will do. Our new initiatives, like the Data and Code section (Arribas-Bel et al., 2021), the re-alignment of the Featured Graphics "from A to B" (Alvanides and Dorling, 2022), and the span of new special issues since the name change reflect this interest.Beyond this re-framing in the present, we wanted to take the opportunity to envision a future for the work published in EPB-What will it be on? How is it done? Who will do it? More importantly to ourselves (and, perhaps, a little selfishly), what would we like to see EPB become in the next 50 years? In this commentary, we look at three dimensions of these questions that we think capture most of these aspects in a structured way: medium, data, and ideas.
MediumAlmost as important to us as what we publish is how we publish it. We believe that a lot of the message can (and should!) be conveyed in the shape, form, and size of the bottle. For that reason, we are excited about the directions in which EPB has always taken the idea of publishing scholarship,
