Gray Notebook archives

The Gray Notebook archives provide access to the past five years of our quarterly analysis of multimodal systems and programs. 

The Gray Notebook analyzes performance trends of multimodal systems and programs for the quarters ending in March, June, September and December each year. Editions are numbered and publish approximately two months after each quarter ends to allow for review and analysis (e.g. for the quarter ending December 30, 2020, the edition was published in late February 2021).

The past five years of Gray Notebooks are listed below and organized by edition number and the quarter we reported on. We can provide earlier PDF editions by request.
