ChronoZoom in 2017 and 2018

An early brainstorming sketch about ChronoZoom in April of 2009

Eight years ago, Walter Alvarez and I dreamed up the idea of a zoomable timeline.
With the endless and generous support of Microsoft Research, Moscow State University, and many friends around the world, ChronoZoom became a reality.

While active development of ChronoZoom ended in 2012, the server has been running continuously since that time. But the web has changed quickly over the last five years. With each year, ChronoZoom’s code becomes more and more difficult to maintain and keep functional.

At the end of 2017, we will be winding down ChronoZoom’s server. On September 1st, 2017 authoring functions will be disabled. Existing timelines will remain online until December 31st, 2017. On January 1st, 2018, timelines will be removed, and the ChronoZoom homepage will display historical project information.

On behalf of all of us that had the opportunity to bring ChronoZoom to life, thank you for using and supporting ChronoZoom all these years. If ChronoZoom has inspired you to think about time or history in new and different ways, I encourage you to discuss new ideas and new projects with others at

Thank you to everyone that believed in the project, brought it to life with their incredible skill and generosity, and most importantly of all, thank you for using ChronoZoom in your classrooms and daily lives to bring history to life!
