The University of Oklahoma has a primary goal: to better the Sooner. Founded in 1890 and known as OU, the university has 20 colleges that offer some 160 bachelor's degrees, 170 master's degrees, and about 80 doctoral degrees through three campuses in Norman, Oklahoma City, and Tulsa. The Norman campus is where the main academic programs reside, while OU's seven health-related professional colleges are based at the Health Sciences Center in Oklahoma City. OU's enrollment has reached about 31,000 students who are instructed by 1,500 full-time faculty members. The university adopted the Sooner nickname in 1908, deriving the moniker from homesteaders who arrived too soon in Oklahoma's 1889 Land Run.
