The Post and Courier, a small newspaper from Charleston, South Carolina, won journalism's biggest honor, taking home the Pulitzer Prize gold medal for service journalism for its work on violence against women.

The series, "Till Death Do Us Part," brought attention to the state's at-risk female population. The Pulitzer citation called the work "a riveting series that probed why South Carolina is among the deadliest states in the union for women and put the issue of what to do about it on the state’s agenda."

The paper's newsroom erupted in cheers as they watched the announcement.

The prizes this year were marked by a heavy focus on fine, detail-oriented investigations of heavy subjects, including Medicare billing and tax loopholes.

The New York Times won the most prizes, with three in total including international reporting. The Seattle TImes won for breaking news. Bloomberg, which was founded in 1990, took home its first Pulitzer, with reporter Zach Mider winning for his explanatory reporting on how corporations avoid taxes.

The Houston Chronicle also won its first Pulitzer award, taking home the prize for commentary for Lisa Falkenberg's work on the abuse of grand juries that led to wrongful convictions.

Carol D. Leonnig of the Washington Post won the national reporting award for her coverage of the Secret Service's numerous lapses.

The local reporting award went to the tiny Daily Breeze of Torrance, California, for alleged corruption by a local school superintendent. The paper employs seven reporters and has a circulation of 63,000.

The Wall Street Journal snapped a cold streak and won its first Pulitzer in several years for non-opinion writing, with the paper's staff wining for its investigative work on "Medicare Unmasked," which delved into the inner workings of health care providers. The Journal was also a finalist with its "Deadly Medicine," series, which the judges called "a stellar reporting project that documented the significant cancer risk to women of a common surgery and prompted a change in the prescribed medical treatment."

The paper celebrated heartily.

The Journal's investigative reporting award is shared with Eric Lipton of the New York Times, who won for his work on lobbyists and their influence in politics.

The Los Angeles Times won in two categories: feature writing for Diana Marcum's series on people affected by the drought in California, and in criticism for Mary McNamara's writing on television.

Kathleen Kingsbury of the Boston Globe won for editorial writing; Adama Zyglis of the Buffalo News won for editorial cartooning. The photography staff of the St. Louis Post-Dispatch won for breaking news photography on the unrest in Ferguson, Missouri; and Daniel Berehulak, a freelance photographer for the New York Times, won for feature photography for his series of photographs on the Ebola epidemic in western Africa.

In the non-journalism awards, Anthony Doerr won for his acclaimed fiction title "All the Light We Cannot See," and the biography prize went to David I. Kertzer for "The Pope and Mussolini."
