Question: In 2011 Walt Anderson was named as a referee for a super bowl held in what stadium?
Context: Dick Hantak (born c. 1938) was an American football official in the National Football League (NFL) for 25 years between 1978 and 2003.  He began his NFL officiating career as a back judge and became a referee eight years later.  During his career, he officiated in two Super Bowls, Super Bowl XVII in 1983 as a back judge and later as a referee in Super Bowl XXVII in 1993, both at the Rose Bowl in Pasadena, California and selected as an alternate for Super Bowl XXXII in 1998.  He was one of the first officials to wear a three-digit uniform number, wearing number 105 except for 1979-81, when officials were numbered separately by position. Tony Steratore has been an American football official in the National Football League (NFL) since the 2000 NFL season, who wears uniform number 112.  He currently works as a back judge.  For the 2017 NFL season, Steratore is the back judge on the officiating crew headed by referee Jerome Boger.  He is a native of the Pittsburgh suburb of Washington, Pennsylvania.  Referee Gene Steratore Jr. is his younger brother.  His father, Gene Steratore Sr., was an official in both college football and basketball.  He officiated two Super Bowl games, which were Super Bowl XXXIX in Jacksonville, Florida, and Super Bowl XLVI in Indianapolis. Super Bowl XXXVII was an American football game between the American Football Conference (AFC) champion Oakland Raiders and the National Football Conference (NFC) champion Tampa Bay Buccaneers to decide the National Football League (NFL) champion for the 2002 season.  The Buccaneers defeated the Raiders by the score of 48–21, tied with Super Bowl XXXV for the seventh largest Super Bowl margin of victory, and winning their first ever Super Bowl.  The game, played on January 26, 2003 at Qualcomm Stadium in San Diego, California, was the sixth Super Bowl to be held a week after the conference championship games (XVII, XXV, XXVIII, XXXIV, and XXXVI).  It was also the last Super Bowl played in the month of January.  Super Bowl XXXVI was the first to be played in February, due to the NFL postponing games for a week after the September 11 attacks.  Starting with Super Bowl XXXVIII in 2004, the Super Bowl has been permanently played in February.  This was the last Super Bowl until Super Bowl 50 to take place in California. Walt Anderson (born c. 1952) is an American football official in the National Football League (NFL) since the 1996 NFL season.  Anderson spent his first seven seasons in the NFL as a line judge before being promoted to referee for the start of the 2003 NFL season after Dick Hantak and Bob McElwee announced their retirements.  He is notable for officiating Super Bowl XXXV.  Anderson was also named as referee for Super Bowl XLV which was played on Feb. 6, 2011, in Arlington, Texas, at Cowboys Stadium.  He wears uniform number 66. Super Bowl XVIII was an American football game between the National Football Conference (NFC) champion Washington Redskins and the American Football Conference (AFC) champion Los Angeles Raiders to decide the National Football League (NFL) champion for the 1983 season.  The Raiders defeated the Redskins by the score of 38–9.  The Raiders, coached by Tom Flores,' 38 points and their 29-point margin of victory broke Super Bowl records; it still remains the most points scored by an AFC team in a Super Bowl.  The game was played on January 22, 1984, at Tampa Stadium in Tampa, Florida, the first time the Super Bowl was held in that city.  This would be the AFC's last Super Bowl win until Super Bowl XXXII, won by the Denver Broncos. Mason L. "Red" Cashion is a former American football official.  He started officiating in 1952 while attending Texas A&M University, and then worked for various high school and college football conferences, most notably the Southwest Conference.  From 1972 to 1996, he officiated in the National Football League (NFL), and was the referee in Super Bowl XX and Super Bowl XXX.  Cashion began his career as a line judge in 1972 following the death of referee Jack Vest, which in turn created an opening at line judge when Chuck Heberling was promoted to referee to replace Vest.  Cashion was promoted to referee in 1976 upon the retirement of long-time referee Norm Schachter and the addition of Seattle and Tampa Bay.  He wore uniform number 43 for most of his career.  During the 1979-1981 seasons, when officials were numbered separately by positions instead of having one number assigned to each official, he wore number 8. Jerry Markbreit (born March 23, 1935) is a former American football referee in the National Football League (NFL) for 23 seasons and became one of the most recognizable referees in the game.  Markbreit officiated football games for 43 seasons.  From 1965 to 1975, Markbreit officiated college football games in the Big Ten Conference.  He then joined the NFL in 1976 as a line judge before being promoted to the head referee position in just his second year.  His uniform number in the league was 9, which is now worn by Mark Perlman.  Until he retired from the NFL after the 1998 season, Markbreit officiated in two wild card (1991 and 1994), ten divisional (1979, 1981, 1982, 1985, 1986, 1987, 1988, 1995, 1997, and 1998), eight conference championship (1980, 1983, 1984, 1989, 1990, 1992, 1993, and 1996) playoff games, one Pro Bowl (1978), and four Super Bowls: Super Bowl XVII, Super Bowl XXI, Super Bowl XXVI, and Super Bowl XXIX and was an alternate in Super Bowl XIX, Super Bowl XXII, and Super Bowl XXVIII.  To date, he is the only NFL head referee to officiate four Super Bowl games. Super Bowl XLV was an American football game between the American Football Conference (AFC) champion Pittsburgh Steelers and the National Football Conference (NFC) champion Green Bay Packers to decide the National Football League (NFL) champion for the 2010 season.  The Packers defeated the Steelers by the score of 31–25.  The game was played on February 6, 2011, at Cowboys Stadium in Arlington, Texas, the first time the Super Bowl was played in the Dallas–Fort Worth area. Super Bowl XLVIII was an American football game between the American Football Conference (AFC) champion Denver Broncos and National Football Conference (NFC) champion Seattle Seahawks to decide the National Football League (NFL) champion for the 2013 season.  The Seahawks defeated the Broncos 43–8, the largest margin of victory for an underdog and tied for the third largest point differential overall (35) in Super Bowl history with Super Bowl XXVII (1993).  It was the first time the winning team scored over 40 points, while holding their opponent to under 10.  This became the first Super Bowl victory for the Seahawks and the fifth Super Bowl loss for the Broncos, the most of any team.  The game was played on February 2, 2014, at MetLife Stadium at the Meadowlands Sports Complex in East Rutherford, New Jersey, the first Super Bowl played outdoors in a cold-weather city and the first Super Bowl to be played on a February 2. The 2007 New York Giants season was the 83rd season for the New York Giants in the National Football League.  The Giants finished the regular season 10–6 and in second place in the NFC East, improving upon their 8–8 record in 2006 in which they finished third in their division.  They qualified for the playoffs as a wild-card team as the #5 seed, and beat the #4 seed Tampa Bay Buccaneers (9–7), the top-seeded Dallas Cowboys (13–3), and the #2 seed Green Bay Packers (13–3) to become the National Football Conference representative in Super Bowl XLII.  There, they defeated the heavily favored and previously undefeated 18–0 New England Patriots and spoiled their perfect season.  The 2007 New York Giants became the 9th wild card team in NFL history to reach the Super Bowl and the 5th wild card team to win the Super Bowl, and the very first NFC wild card to accomplish the feat.  They were the third team in history to win three road playoff games en route to a Super Bowl and set a league record for most consecutive road wins in a single season (11), though the Super Bowl is played on a neutral field rather than an opponent's stadium.  It was the 7th league championship season for the New York Giants and their first since they won Super Bowl XXV in 1991.
