Ohio Stadium, also known as The Horseshoe or “The Shoe” or “The House that Harley built”, is an American football stadium in Columbus, Ohio, United States, on the campus of The Ohio State University. Its primary purpose is the home venue of the Ohio State Buckeyes football team and the Ohio State University Marching Band. From 1996–98, Ohio Stadium was the home venue for Major League Soccer team Columbus Crew prior to the opening of Columbus Crew Stadium in 1999. The stadium also was the home venue for the OSU track and field teams from 1923–2001. In addition to athletics, Ohio Stadium is also a concert venue, with U2, The Rolling Stones, Pink Floyd, and Metallica among the many acts to have played there, and also serves as the site for the university’s Spring Commencement ceremonies each May. Permanent field lights were added in 2014.
The stadium opened in 1922 as a replacement for Ohio Field and had a seating capacity of 66,210. In 1923, a cinder running track was added that was later upgraded to an all-weather track. Seating capacity gradually increased over the years and reached a total of 91,470 possible spectators in 1991. Beginning in 2000, the stadium was renovated and expanded in several phases, removing the track and adding additional seating, which raised the capacity to 101,568 by 2001 and to 102,329 in 2007. In 2014, additional seating was added in the end zone, raising the official capacity to 104,944. It is the largest stadium by capacity in the state of Ohio,the third largest football stadium in the United States, and the fourth largest non-racing stadium in the world. Ohio Stadium was added to the National Register of Historic Places by the National Park Service on March 22, 1974.
The first game in the stadium was against Ohio Wesleyan University on October 7, 1922, and brought a crowd of around 25,000, which left people concerned because the stadium was half empty. This concern was put to rest at the stadium’s formal dedication against Michigan on October 21, which the Wolverines won, 19–0. The crowd was announced at the game to be 72,000, but no one is really sure how many people made it into the stadium. This attendance mark was broken in a game against Michigan in 1925 when 90,411 came out to support the Buckeyes; this is also the last time standing-room-only tickets were sold for a game.
The stadium did not regularly sell out until after WWII, and in the 1920s and 1930s most games only drew in 20,000 or 30,000 fans with many more attending the annual game against Michigan. The 1935 contest withNotre Dame was a sellout, with over 81,000 in attendance.
In 1923, a cinder track was built around the football field, which would later be named after Olympian and Ohio State athlete Jesse Owens. The stadium was home to the OSU track and field teams until the opening ofJesse Owens Memorial Stadium in 2001.
On September 27, 2014, after 2,500 seats were added in a stadium expansion, a record crowd of 108,362 attended the Cincinnati game where the #22 ranked Buckeyes won 50-28. The previous record crowd of 107,517 attended the Virginia Tech game which the #8 ranked Buckeyes lost 35- 21. The previous largest crowd at Ohio Stadium was 106,102 for the Buckeyes’ 63–38 win over the Nebraska Cornhuskers on October 6, 2012.The next previous record of 106,033 was set in 2009, in an 18–15 loss to the USC Trojans. In 2002, Mel Kiper, Jr. ranked Ohio Stadium second in atmosphere, behind the Army-Navy Game, and quoted Beano Cook in saying “There is nothing that beats when the Ohio State Marching Band and the sousaphone player dots the ‘i’ for Script Ohio.” 
The crowd attending these home games is known for creating harsh and difficult environments for opponents. University of Iowa coach Hayden Fry complained after a 1985 loss that the fans were too loud for his quarterback, Chuck Long, to call plays and suggested sound meters be used to gauge the noise level, penalizing home teams if there was too much noise. He said, “It’s a realistic fact that happened. He became mentally disturbed for the first time since he’s been a starter for us because of his inability to communicate.”
O-H-I-O and “Seven Nation Army”
One famous chant by the Buckeye fans, usually starting with the students in the South Stands, is O-H-I-O. The entire South end yells O then the East stands follow with H, the North with I and the West with O. The chant loops around the stadium loudly sometimes for 5 to 10 minutes. Before kick off the entire stadium screams O continuously until the ball is kicked, immediately following the kick the stadium shouts in unison O-H-I-O.
After big plays or before kickoffs the loudspeakers play “Seven Nation Army” by the band The White Stripes. The entire crowd at the stadium, pumped up after said events, will usually sing along and jump up and down to the beat.
