In 2006, Popović and two of his former Otpor colleagues, now CANVAS members - Slobodan Đinović and Andrej Milivojević - authored a book called "Nonviolent Struggle: 50 Crucial Points", a how-to guide to nonviolent struggle, which can be downloaded for free in six languages from their website. The book was financed with a grant from the United States Institute of Peace (USIP), an organization founded and funded by the U.S. Congress. The book has been downloaded some 20,000 times in the Middle East, mostly by Iranians. Due to their involvement in regime changes all around the globe, CANVAS has been labeled "Academy of Revolution" while Popović and others involved in the organization have been referred to by various media outlets as "professors of revolution", "revolution consultants", "professional revolutionaries", and "revolution exporters".
