Copley's family influenced nearly every facet of life in the San Diego region during the eight decades of newspaper ownership, with its endorsement of select politicians and support of economic development projects and educational ventures such as the establishment of UC San Diego. His mother, Helen, married James Copley, then the publisher, in 1965. For several decades, the Copley Press published the San Diego Union and the Evening Tribune; in 1992 the papers merged. After James Copley died in 1973, Helen Copley assumed control of the newspapers. David Copley became publisher in 2001, three years before his mother's death. But as the newspaper industry's economic fortunes waned, David Copley sold the newspapers and, in effect, retired from public life. David Copley financed Broadway musicals and art projects by the artist Christo. Shy and uncomfortable in public settings, he nonetheless enjoyed world travel, particularly on his yacht, and entertained lavishly at his home in La Jolla. With David Copley as publisher, the newspaper won a Pulitzer Prize in 2006 for exposing the corruption of a leading Republican, Rep. Randall "Duke" Cunningham. In 2009, David Copley sold the remaining newspaper interests to a private equity group, which later sold it to developer-hotelier "Papa Doug" Manchester, who renamed the paper the U-T San Diego.
