(IOC). The resulting 3-D presentation, developed by the institute's Multimedia Laboratory, provided a "1996" view of Atlanta, complete with digitized graphic models of non-existent facilities overlaid on their proposed sites. More than 40 Georgia Tech computer scientists were recruited to assemble the virtual reality, three-dimensional tour through Olympic venues that had not yet even been designed. The term "virtual reality" was almost unknown in 1989 when Tech's seven-foot tall, three-screen, 3-D interactive video and laser disc projection system debuted during a meeting of the IOC at San Juan, Puerto Rico. Members of the committee used a trackball and a touch screen to view a dazzling montage of animation, computer graphics, aerial photography, video, and satellite topographical photographs created to depict Atlanta during the Centennial Olympic Games. Many believe the presentation showed the IOC that Atlanta was a major player in its Olympics bid and served to create the foundation for the city's high-tech theme for the Centennial Games. After Atlanta won the Olympics bid, a dramatic amount of construction occurred, creating most of what is now considered "West Campus" in order for Tech to serve as the Olympic Village. The Undergraduate Living Center, Fourth Street Apartments, Sixth Street Apartments, Eighth Street Apartments, Hemphill Apartments (now known as Crecine Apartments), and Center Street Apartments housed athletes and journalists. The Georgia Tech Aquatic Center was built for swimming events, and the Alexander Memorial Coliseum was renovated. Modern history (1994–present) In 1994, G. Wayne Clough became the first Tech alumnus to serve as the President of the institute. The 1996 Summer Olympics took place in Atlanta early in Clough's tenure. In 1998, he split the Ivan Allen College of Management, Policy, and International Affairs, creating the Ivan Allen College of Liberal Arts and returning the College of Management to "College" status. During his tenure, research expenditures increased from $212 million to $425 million, enrollment increased from 13,000 to 18,000, Tech received the Hesburgh Award, and Tech's U.S. News & World Report rankings steadily improved. Clough's tenure especially focused on a dramatic expansion and modernization of the institute. Coinciding with the rise of personal computers, computer ownership became mandatory for all students in 1997. In 1998, Georgia Tech was the first university in the Southeastern United States to provide its fraternity and sorority houses with internet access. A campus wireless network, the Local Area Wireless/Walkup Network (LAWN), was established in 1999; it now covers
