She has co-coordinated Paper Tiger installations at the Whitney Museum of American Art, the Austrian Triennial of Photography in Graz, the Wexner Center in Columbus Ohio, the Gallery at the San Francisco Art Institute and the Berkeley Art Museum. In 1990, before the first Gulf War started, she worked with a team of Paper Tiger and Deep Dish producers to create a series on the impending war, called The Gulf Crisis TV Project which ultimately produced ten half-hour programs which were widely shown on Public-access television stations, film festivals, the Whitney Museum, Channel Four in the UK and NHK in Japan. Her work with Deep Dish TV includes a twelve part series on the prison industrial complex in the United States entitled, Bars and Stripes and Shocking and Awful, a thirteen part series on the 2003 invasion and occupation of Iraq. She is currently finishing a four-hour compilation of speeches and interviews from the World Tribunal on Iraq, which Deep Dish filmed in Istanbul in June 2005. Halleck has been closely involved with the Independent Media Center movement, which now totals over 180 centers in sixty countries. She was one of the initial group of media activists that developed the first center in Seattle during the World Trade Organization protests. Her role was to develop the initial funding proposal for the center, raise funds from individual donors and organize 5 days of satellite broadcasting from that historic event. That work evolved into the television version of Democracy Now!, the Pacifica Network daily radio news series. After retiring from the University of California in 2001, Halleck worked full-time for a year to create the infrastructure and resources for Democracy Now! television, building on the contacts already established by Deep Dish. This daily news program is now on over 650 community television and radio stations and on the Dish Network of 15 million subscribers via Freespeech TV. As President of the Association of Independent Video and Film Makers in the nineteen seventies, Halleck led a media reform campaign in Washington, testifying twice before the House Sub-Committee on Telecommunication for increased support and channel space for independent video and film. This work ultimately lead to the creation of ITVS, the Independent Television Service. Halleck’s work in media reform includes working with a coalition of national organizations to insure public interest set-asides for Direct Broadcast Satellite. That successful campaign created the provisions which have allowed Free Speech TV, Link TV and a number of universities to have 24-hour television networks via satellite. Halleck has been involved in media policy reform on the international level as a member of the MacBride Roundtable on Communication, Communication Rights in the Information Society and as an official delegate to the World Summit on the Information Society in Geneva 2003 and in Tunis in 2005. Halleck is now working with Victoria Maldonado on a series entitled "Waves of Change", which looks at community mediaaround the world.
