Darrell K Royal–Texas Memorial Stadium

In 1923, former UT athletics director L. Theo Bellmont (the west side of the stadium is named in his honor), along with 30 student leaders, presented the idea of building a concrete stadium to replace the wooden bleachers of Clark Field to the Board of Regents. Heralded as "the largest sports facility of its kind in the Southwest" upon its completion in 1924, it seated 27,000 people in the lower level of the current facility's east and west grandstands. It was designed as a dual-purpose facility with a 440-yard (400 m) track surrounding the football field. The stadium was financed through donations from both students and alumni. The estimated cost of the structure was $275,000.

The student body dedicated the stadium in honor of the 198,520 Texans – 5,280 of whom lost their lives – who fought in World War I. A statue, representing the figure of democracy, was later placed atop the north end zone seats of the stadium. In World War II, the University lost many former players, including former coach Jack Chevigny. The Athletics Council rededicated the newly enlarged stadium on September 18, 1948 prior to the Texas-LSU game, honoring the men and women who had died in the war. On November 12, 1977, a small granite monument was unveiled and placed at the base of the statue, during the TCU-Texas game. The ceremony rededicated Texas Memorial Stadium to the memory of all alumni in all American wars.

The University of Texas honored legendary football coach Darrell K Royal, who enlisted in the US Army Air Corps in 1943, played at the University of Oklahoma under legendary Coach Bud Wilkinson, and who led Texas to three national championships and eleven Southwest Conference titles, by officially naming the stadium after him in 1996. Additionally, the University established the Royal-Texas Memorial Stadium Veterans Committee, composed of alumni who served in World War II, Korea, Vietnam or the Gulf Wars. The committee is charged to forever dedicate the stadium in the memory of, and in honor of, UT students and alumni who gave their lives for their country. Each year, one home football game is designated as Veterans Recognition Day, commemorating the memorial aspect of the stadium and to honor the memory of war soldiers.

Smokey the Cannon (lower left) is in the eastern section of the north end zone. The 2007 expansion brought the seats closer to the field so the cannon was relocated to the southeastern corner of the stadium.

The stadium has been expanded several times since its original opening.[6]

The expansion included additional seats with an upper deck, club space, suites, athletic offices, academic-advising areas and a basement with gym space. Demolition of the old north end zone began on December 8, 2006 to move seating closer to the field.[7] The south end zone also became the new seating location of the Longhorn Band beginning in 2008. Overall, the stadium's official seating capacity increased to 94,113.[8]

• 2019 – The final planned phase of the stadium's expansion includes construction of permanent seating in the south end zone, completely enclosing the playing field. Plans include club seating, luxury suites, and new video board. This plan has been part of the University's master plan since at least the early 1990s, as renderings and models of a fully enclosed stadium have existed since that time. On September 20, 2018, the University announced that it will spend $175 million on the south end zone project[14] with most of the funds coming from donations.[15] The south end zone will not mirror the north end zone and seating capacity has not been announced.[14] On May 4, 2019, ground was broken on the "south-end zone expansion project". "The new addition is set to open for the 2021 football season."[16]
• 2020 – In response to calls for increased diversity at the university and at the suggestion of the Jamail family, interim president Jay Hartzell announced that the field, previously named for Joe Jamail, would be renamed to honor Heisman Trophy winners Earl Campbell and Ricky Williams. Hartzell also announced that a statue of Julius Whittier, the school's first Black football letterman, would be erected at the stadium.[17][18]

The scoreboard measures at 55 feet (17 m) tall and 134 feet (41 m) wide with a pixel resolution of 2064 x 848.[19] The scoreboard was installed as part of a US$149.9 million stadium renovation, $8 million of which was spent on audiovisual improvements. The new HD screen was the centerpiece of these improvements and debuted at the start of the 2006 football season.[20] Previously, two scoreboards were in place, one in the south end, the Freddie Steinmark Memorial Scoreboard and Jumbotron, and one in the north end, a video matrix screen. Both were removed after the 2005 season. The new scoreboard replaced the one in the south end. The north end no longer features a scoreboard as it was removed for the 2008 stadium expansion, the giant Longhorn symbol at the very top was sold on eBay.[21] On November 8, 2015, the UT Longhorns rededicated the scoreboard to Freddie Steinmark in a ceremony attended by many previous Longhorn players.[22]

At the time of its creation, it was called the largest HD video screen in the world,[20][23] though it was quickly surpassed by a larger screen in Tokyo.[24][25]

The screen was controversial among fans because at some times a large portion (more than 50%) of the screen was being used for advertising and other non-game related graphics. This has led to some fans (including Austin American-Statesman commentator Kirk Bohls) calling the new screen "Adzillatron". Complaints have also been made about the scoreboard being too loud and about it broadcasting advertisements to those in the stadium, even over the top of the band playing in the stadium. In its first usage, the portion of the new screen that was typically used for showing replays and film highlights was approximately the same size as the old video screen. More recent games have featured a 16:9 format image centered in a ring of advertisement and score/clock related information.
