[RecSys 2026] Call for Submissions — 20×20 Retrospective Track

*Call for Submissions — 20×20 Retrospective Track* Let’s celebrate together
20 years of RecSys

This year marks the 20th anniversary of the ACM Conference on Recommender
Systems. As part of the celebrations, the General Chairs have allocated
time for a special 20×20 Retrospective Track, reflecting on 20 milestones
over the 20 years that have shaped our research community and sustained its
growth.

Chaired by Robin Burke, a group of researchers and practitioners
representing different corners of the RecSys community has curated a list
of 20 milestones — among the many that have impacted our field — spanning
three categories: Foundations, Applications, and Community.

Now we need your help.

*What we're asking for. *Take a look at the 20 milestones:
https://that-recsys-lab.net/home/pubs/recsys2026_milestones_reference.pdf

Once you've reviewed them, choose the one you feel most connected to and
submit a short video reflecting on its personal impact. Why was this
milestone significant to you as a member of our community? What did it
change, unlock, or make possible in your own work or perspective?

We're not looking for a comprehensive history — we're looking for genuine,
personal reflection.
*Requirements.*

●       One submission per person. You may submit only a single video, so
choose your milestone wisely.

●       Submit your file in MP4 format with a 16:9 horizontal aspect ratio.
Name the file using the format: Milestone-LastName.

●       Keep it short. Videos may be at most 1 minute. A pithy, meaningful
video is always preferable to a long one.

●       Consent to share. If selected, you agree that your video may be
shown during the main conference and added to a special playlist on the ACM
RecSys YouTube channel.

*Submission process & timeline. *Submit your video via EasyChair:
