Editor and Publisher details "a secret arrangement formed more than 10 years ago" where the New York Times and Washington Post "send each other copies of their next day's front pages every night."
"When the swap first began in the mid-'90s, each paper would fax copies of its Page One layout," according to Post editor Len Downie, "adding that he does not remember which paper proposed the idea first. In recent years, they have moved to electronic transmissions of the front pages, usually sent between 10:30 and 11 p.m."
