Big news today at One Herald Square: Kevin Convey, a longtime Herald veteran who’s been editor-in-chief for the past three-plus years, is leaving to become editor of New York’s Daily News. He replaces Martin Dunn, whose departure was reportedly prompted by his wife’s battle with cancer.

I haven’t seen this mentioned anywhere, but Dunn was editor of the Herald for a very brief period in the early 1990s.

Convey’s new job entails a switch of tabloid loyalties. In Boston, the Herald is allied with its former owner, Rupert Murdoch. Herald publisher Pat Purcell, who bought the paper from his old boss in 1994, helps Murdoch run regional properties such as the Standard-Times of New Bedford and the Cape Cod Times.

In New York, the Daily News — owned by real-estate mogul Mort Zuckerman, who also has significant Boston ties — has been entangled for years in a steel-cage death match with the New York Post, whose owner, of course, is Murdoch. Here is the Daily News’ press release, along with Convey’s reaction:

I am looking forward to the challenge of editing the Daily News, which has some of the most talented people in the newspaper business and the web anywhere in the world. It is a great privilege.

Convey’s a smart guy who took over the Herald at a time when the paper, and the news business in general, was shrinking drastically. During the 1990s, he was part of the triumvirate that ran the paper, serving as managing editor for features along with editor Andy Costello and managing editor for news Andrew Gully. The trio was known, sometimes affectionately, sometimes not, as the “Micks with Dicks,” a commentary on their aggression as much as it was on their ethnicity.

Convey became editor-in-chief of Community Newspaper Co., which published about 100 papers in Eastern Massachusetts, when Purcell added it to his holdings in the early 2000s. After Purcell sold CNC to GateHouse Media a few years later, Convey returned to the Herald, serving as the paper’s number-two while editorial director Ken Chandler, tarted it up and made it more gossipy — more of a tabloid, if you like. After Chander moved on, Convey took over.

Howard Kurtz of the Washington Post wrote about Convey’s Herald in 2008.

Best of luck to Convey, who’s a good guy, and whom I generally found to be helpful and accessible back when I was covering the local media for the Boston Phoenix.

Needless to say, it will be fascinating to see who ends up succeeding Convey at the Herald.

Update: Well, that didn’t take long.

Correction: Ken Chandler’s name now fixed, thanks to an alert reader.
