Usenix ATC Announcement

Summary

USENIX celebrates its 50th anniversary in 2025. We celebrate decades of innovations, experiments, and gatherings of the advanced computing system community. And in the spirit of our ever-evolving community, field, and industry, we announce the bittersweet conclusion of our longest-running event, the USENIX Annual Technical Conference in July 2025, following USENIX ATC '25. Since USENIX's inception in 1975, it has been a key gathering place for innovators in the advanced computing systems community. The early days of meetings evolved into the two annual conferences, the USENIX Summer and Winter Conferences, which in 1995 merged into the single Annual Technical Conference that has continued to evolve and serve thousands of our constituents for 30 years. For the past two decades, as more USENIX conferences have joined the USENIX calendar by focusing on specific topics that grew out of ATC itself, attendance at ATC has steadily decreased to the point where there is no longer a critical mass of researchers and practitioners joining us. Thus, after many years of experiments to adapt this conference to the ever-changing tech landscape and community, the USENIX Board of Directors has made the difficult decision to sunset USENIX ATC. USENIX ATC in its many iterations has been the home of an incredible list of "firsts" in our industry: In 1979, ONYX, the first attempt at genuine UNIX hardware, was announced. In 1982, DEC unveiled the creation of its UNIX product. In 1983, Eric Allman presented the first paper on Sendmail, "Mail Systems and Addressing in 4.2BSD." In 1985, Sun Microsystems presented the first paper on NFS, "Design and Implementation of the Sun Network Filesystem." In 1988, the first light on Kerberos and the X Window system was presented. In 1989, Tom Christiansen made his first Perl presentation as an Invited Talk. In 1990, John Ousterhout presented Tcl. In 1995, the first talk on Oak (later JAVA) was given as a Work-in-Progress report. In 1998, Miguel de Icaz...
