San Diego Union-Tribune
California. The result of a February 2, 1992, merger of The San Diego Union, founded October 10, 1868, and the Evening Tribune, founded December 2, 1895, it refers to itself as the oldest business in San Diego County and the second-oldest newspaper in Southern California. The website Signonsandiego.com republishes much of the Union-Tribune's content as well as publishing its own material. The Union-Tribune and Signonsandiego.com are separate businesses with separate staff.
