The United Nations has its own news and media service that reports on numerous topics that fall within its broad global remit, including the HIV epidemic in Africa, military conflicts in the Middle East, and economic development. On this website, visitors can learn about the UN's array of multimedia programs, including its radio programs, videos, and photographic archives. The UN News Centre will be of great interest to visitors, as they may read about the various activities of the UN, and read newsbriefs by region or various statements and briefings released by the spokesman for the Secretary General. Another section of interest is the United Nations Radio News, which allows visitors to listen to a short radio news program (approximately 15 minutes in length) produced five days a week. Visitors may also listen to previous news reports dating back to January 2004. The photo section is quite nice as well, as it contains selections from the almost 240,000 photographs taken to document the UN's activities since its creation close to sixty years ago. Visitors may browse through thematic collections (such as those dedicated to topics like East Timor and landmines) or peruse a pictorial history of the UN, which includes photographs of such important leaders as Dag Hammarskjold.
