Founded in about 1765, the American Whig-Cliosophic Society is the nation's oldest collegiate political, literary, and debate society, and is the largest and oldest student organization on campus. The Whig-Clio Society has several subsidiary organizations, each specialized to different areas of politics: the Princeton Debate Panel, International Relations Council, Princeton Mock Trial, and Princeton Model Congress. The International Relations Council manages two Model United Nations conferences: the Princeton Diplomatic Invitational (PDI) for collegiate competition and the Princeton Model United Nations Conference (PMUNC) for high school competition. There are several publications on campus and a radio station. Founded in 1876, The Daily Princetonian, otherwise known as The Prince, is the second oldest college daily student newspaper in the United States. Other publications include The Nassau Literary Review, the Princeton Tory, a campus journal of conservative thought, The Princeton Diplomat, the only student-run magazine on global affairs, the Princeton Political Review, the only multi-partisan political publication on campus, and the recently revived Princeton Progressive, the only left-leaning political publication on campus, among others. Princeton's WPRB (103.3 FM) radio station is the oldest licensed college radio station in the nation. Princeton is home to a variety of performing arts and music groups. Many of the groups are represented by the Performing Arts Council. Dating back to 1883, the Princeton Triangle Club is America's oldest touring musical-comedy theater group. It performs its annual Triangle Show every fall at the 1,000 seat McCarter Theatre, as well as original musical comedies, revues, and other shows throughout campus. Princeton's oldest choir is the Glee Club, which began in 1874. The comedic scramble Tiger Band was formed in 1919 and plays at halftime shows and other events. Other groups include the Princeton University Orchestra, the flagship symphony orchestra group founded in 1896, and the Princeton Symphony Orchestra, both of which perform at Alexander Hall. A cappella groups are a staple of campus life, with many holding concerts, informal shows, and arch sings. Arch sings are where a cappella performances are held in one of Princeton's many gothic arches. The oldest a cappella ensemble is the Nassoons, which were formed in 1941. All-male groups include the Tigertones (1946) and Footnotes (1959); all-female groups include the Tigerlilies (1971), Tigressions (1981), Wildcats (1987); the oldest coed a cappella group in the Ivy League is the Princeton Katzenjammers (1973), which was followed by the Roaring 20 (1983) and Shere Khan (1994).
