Founded by Ysiad Ferreiras
in Union Square in lower Manhattan, the group expanded to include hundreds of for-profit activists who spread the group's message at both national political conventions in 2004 and at speeches across the country. The shirts were especially effective in mobilizing political activity on college campuses. Ben Piven became the director of PR, political activism, and national distribution, while Marty Taylor took charge of Disarm Bush's internet campaign.
Eventually popularized by the Roots, Yeah Yeah Yeahs, and The Flaming Lips, the Disarm Bush logo became a simple but powerful expression of disapproval of the incumbent's performance in office. The Republican National Convention, which lasted from August 30 to September 2, saw the emergence of hundreds of similar t-shirt campaigns in which vendors attempted to spread their political dissent via the estimated 500,000 marchers who converged upon New York City to protest the presence of Republicans in a largely Democratic Party urban area. The 2004 Republican National Convention protest activity created an unprecedented level of political mobilization and also posed security problems.
