New York (CNN Business) Time magazine has chosen "The Guardians," a group of journalists who have been targeted for their work, as Person of the Year.

A series of four black-and-white covers highlights what the magazine calls "the War on Truth."

The group includes Jamal Khashoggi, the Washington Post contributor who was killed at the Saudi Arabian consulate in Istanbul in October. This is the first time that a Person of the Year is a deceased person.

Another cover features Wa Lone and Kyaw Soe Oo, two Reuters journalists who were arrested one year ago in Myanmar while they were working on stories about the killings of Rohingya Muslims, a minority population in Myanmar's Rakhine state. The two men remain behind bars. Their wives were photographed for the cover.

"The Guardians" also includes the journalists at the Capital Gazette, the Annapolis, Maryland newspaper where five employees were murdered by a gunman last June.
