the Prohibition Era. He was closely allied with James Dahlman, Omaha's only eight-term mayor. Dennison was implicated in agitation of groups related to the Omaha Race Riot of 1919. World War II In 1945 the Enola Gay and Bockscar were two of 536 B-29 Superfortresses manufactured at the Glenn L. Martin Aircraft Factory (now Offutt Air Force Base) in suburban Bellevue. That same year a Japanese fire balloon exploded over Dundee. The incident was part of a large World War II campaign by the Japanese military to cause mass chaos in American cities. The story was suppressed by the American military until after the war was over, as no one was hurt in the explosion. Civil Rights Movement Era Civil rights activism in Omaha began in 1912 with the formation of a local chapter of the National Association for the Advancement of Colored People. It continued through the coming years under the influence of local leaders Whitney Young, George Wells Parker and Harry Haywood. Other organizations formed such as the Citizens Civic Committee for Civil Liberties (4CL) and the DePorres Club at Creighton University in the 1940s. Mainstream organizations including the Omaha Urban League (now the Urban League of Nebraska) also supported the movement, as did the CIO union in the meatpacking plants. Their successes led to the end of redlining and discriminatory neighborhood covenants, as well as the implementation of a school integration plan. In the late 1960s, the student-led Black Association for Nationalism Through Unity (BANTU) adopted a more militant posture and got into confrontations with police following the shooting of a youth in the housing project. Transformative Era: 1950 to 1999 In 1950, the NCAA moved the College World Series (CWS) to Rosenblatt Stadium, (then known as Omaha Municipal Stadium). Started in 1947, the tournament was held at Kalamazoo, Michigan in 1947 and 1948, and Wichita, Kansas in 1949. Since 1950 the series has been held annually at the Rosenblatt, despite bids from several cities to move the CWS to another venue. More than 6,000,000 fans have attended CWS games in Omaha. The City of Omaha has regularly expanded and renovated the stadium to accommodate fans, teams, and media covering the event. ESPN televised every game of the event from 1980 through 1987. ESPN started coverage again when the championship series went to a best-of-3 format in 2003. From 1988 through 2002, CBS televised the championship game:
