In 1967, the center was expanded to include the Convention Hall, built specifically for the Democratic and Republican conventions. It also served as a sports arena until the 1980s.
In August 1961, the Convention Center was the meeting place for a youth convention set up by The American Lutheran Church. Among the notable speakers was Dr. Martin Luther King Jr.
From 1960 to 1971, and again in 1997, the center was the site of the Miss Universe pageant. It also hosted a 1961 Billy Graham Crusade and hosted the 1968 Republican National Convention, 1972 Republican National Convention, and the 1972 Democratic National Convention.
In 1989, the facility underwent a $92 million renovation and doubled in size. In the last six years,[when?] the facility has had over $35 million in continuing upgrades, including complete renovations of all restrooms, full carpet replacement, and installation of a state-of-the-art telecommunications and networking infrastructure.
