In 1999, the arena received funds to complete a major interior and exterior renovation. By 2008, new visual equipment was installed including a 4-sided LED scoreboard, a new shot clock system for the backboards, six wall-mounted locker room game clocks, two custom scoreboards which include player stats, and an outdoor marquee LED billboard. These upgrades made the arena more advanced and allowed for other opportunities. In 2001, the Cox Pavilion, a smaller arena, was added to the facility for smaller events such as women’s basketball and volleyball.
The arena was previously nicknamed “The Shark Tank” after coach Jerry Tarkanian, the head coach during the arena’s opening, won a national championship and led the team to three Final Fours in 1990. Other events held at the stadium include the 1994-1995 Big West Conference, 1997-1999 Western Athletic Conference, and the 2000-2003 Mountain West Conference. The Mountain West Conference stayed at the arena from 2007 to 2013. In 2007, for the first time in NBA history, an on-campus college sports arena held an NBA All-Star Game.

In 1984, Kareem-Abdul-Jabbar broke Wilt Chamberlain’s record for points in a career. In 1992, the Lakers used the arena for Game 4 of their playoff series. The center hosted the Los Angeles Lakers pre-season games annually until 2014.
Numerous football games have been played in the Thomas and Mack Center. In fact, the arena was formerly the home to the Las Vegas Sting, Las Vegas Gladiators, and the Las Vegas Outlaws.
