The spot aired in the fourth quarter and was one of the only commercials not to previously be released online.
The advertisement showed several journalists who'd gone missing or been killed, including Jamal Khashoggi, who was murdered at the Saudi Arabian Consulate in Istanbul in October; Austin Tice, who's been missing in Syria for six years; and Marie Colvin, an American war correspondent for The Sunday Times of London, who was killed in Syria in 2012.
Deadline estimates that The Washington Post spent upwards of $5 million for the ad.
