The San Diego Union-Tribune is a metropolitan daily newspaper published in San Diego, California, that has run since 1868. Its name derives from a 1992 merger between the two major daily newspapers at the time, The San Diego Union and the San Diego Evening Tribune. The name changed to U-T San Diego in 2012 but was changed again to The San Diego Union-Tribune in 2015. In 2015, the newspaper was acquired by Tribune Publishing.
