A.G. Sulzberger, 37, to Take Over as New York Times Publisher

In a generational changing of the guard, Arthur Gregg Sulzberger, 37, will become the publisher of The New York Times on Jan. 1. His father, Arthur Ochs Sulzberger Jr., announced on Thursday that he was turning over the post to his son.

The ascension of the younger Mr. Sulzberger, who is known as A. G., comes just over a year after he was named deputy publisher of The Times. The New York Times Company’s board voted in favor of the move during a meeting on Thursday.

The elder Mr. Sulzberger, 66, who will stay on as chairman of The New York Times Company, has been the publisher since 1992.

“This isn’t a goodbye,” Mr. Sulzberger said in a note to Times employees on Thursday. “But, beginning in the new year, the grand ship that is The Times will be A. G.’s to steer.”

Best known for heading the team that produced The Times’s “innovation report” in 2014, A. G. Sulzberger will be the sixth member of the Ochs-Sulzberger family to serve as publisher since its patriarch, Adolph S. Ochs, purchased the paper in a bankruptcy sale in 1896.

“I am an unapologetic champion for this institution and its journalistic mission,” A. G. Sulzberger said. “And I’ll continue to be that as publisher.”
