The Arizona Daily Star is the major morning daily newspaper that serves Tucson and surrounding districts of southern Arizona in the United States. The paper was purchased by Pulitzer in 1971; Lee Enterprises bought Pulitzer in 2005.
The Star was in a joint operating agreement with the Tucson Citizen, a smaller paper owned by Gannett (and was Tucson's afternoon paper six days per week, except Sunday, when the Star published Tucson's only Sunday paper), until that paper became online only. The two newspapers, under TNI Partners, shared business and production operations but maintained separate newsrooms and editorial staffs.
In 1981, Star reporters Clark Hallas and Robert B. Lowe won a Pulitzer Prize for their stories about recruiting violations by University of Arizona football coach Tony Mason.
In 2012, the newspaper ran a popular series called 100 Days of Science by reporter Tom Beal. It was later turned into an ebook. Other popular series run in the "Star" are Tucson Oddity which has run for several years and Street Smarts which launched in mid-year 2012 by reporter David Leighton. The Star currently does not have a bureau in the state capital, Phoenix, and instead relies on an outside news service.
