KGOU is affiliated with NPR. The campus newspaper, "The Oklahoma Daily", is produced daily during the fall and spring semesters and weekly during the summer semester. "The Oklahoma Daily"s sister publication, "Sooner" yearbook, creates a 400-page coffee table book for current students and alumni. "Sooner", ranked as one of the top two yearbooks nationwide, focuses on capturing the year with storytelling packages of text, photos and design. The University of Oklahoma's Pre-Law Program fields a mock trial team that was founded in 2015. The team competes under the American Mock Trial Association in tournaments across the country. The University of Oklahoma College of Law hosts the only annual regional competition in the state of Oklahoma. In 2019, OU qualified for the American Mock Trial Association Opening Round Championship Series. The University of Oklahoma is also home to the Oklahoma Weather Lab (OWL), one of the nation's only entirely student-run forecasting organizations. In addition to creating daily forecasts for twelve sites across Oklahoma and Key West, Florida, the organization also offers the podcast "Talking Up a Storm" that are available on iTunes for free. Oklahoma has a strong social fraternity and sorority presence. Many fraternities and sororities are only a couple decades younger than the university itself with the first fraternity chapter established in 1905 and Kappa Sigma (the Gamma-Kappa Chapter) established in 1906. The Tau Epsilon Nu chapter, established in 2011, is the newest fraternity chapter at the university. Currently there are 40 national fraternities and sororities on campus. Governing these 40 Greek chapters are four governing bodies: Interfraternity Council, Panhellenic Association, National Pan-Hellenic Council, and the Multicultural Greek Council. In 2005, the average GPA for the Panhellenic Association was 3.30. The school's sports teams are called the Sooners, a nickname given to early settlers during the land run who sneaked into the offered territory and staked claims illegally before they were officially allowed to. They participate in the NCAA's Division I-Bowl Subdivision and in the Big 12 Conference. The school sponsors nine sports for both men and women. The university has claimed 36 team national championships, which includes 7 football national championships (football championships are not awarded by the NCAA). By far, OU's most famous and storied athletic program is the football program, which has produced seven Heisman Trophy winners: Billy Vessels in 1952, Steve Owens in 1969, Billy Sims in 1978, Jason White in 2003, Sam Bradford in 2008, Baker Mayfield in 2017, and Kyler Murray in 2018.
