After 15 years editing New York magazine, Editor in Chief Adam Moss will step down on March 31.

In a memo to staff Tuesday, Moss said “editors ought to have term-limits. Experience is good, but after a while, every institution needs a blood transfusion,” he added.

Moss told The New York Times that at 61, “I’m older than the staff. I’m older than the readers. I just want to do something new.”

Moss led the digital transformation of New York from a print publication to a successful digital operation, launching five online verticals at New York Media: Vulture for entertainment, The Cut for women’s culture and lifestyle, Intelligencer for politics and news, The Strategist for online shopping and Grub Street for food and restaurants.

New York introduced a dynamic metered paywall last year, with subscriptions priced at $5 a month. For $70 a year, digital subscriptions include the biweekly New York print magazine.

After Moss officially steps down, he will remain as an informal adviser to New York Media CEO Pam Wasserstein.

“Adam showed the world that a legacy print publisher could lead invention in digital products, that a brand with local origins could own national conversations, that a diversified premium media business can be constructed around an original editorial voice,” Wasserstein stated.

The magazine and its digital publications won 40 National Magazine Awards under Moss’ leadership, according to the company.

Moss edited The New York Times Magazine for five years beginning in 1998, and also created the Styles section of The Times.

Wasserstein is expected to announce a successor in the coming days, according to The New York Times.

The Wall Street Journalreported last year that Wasserstein may be exploring the sale of New York Media, but there are yet to be moves in that direction. 

Moss joins a number of longtime top magazine editors that have stepped down in the last few years. Cindi Leive left Glamour after 16 years, Graydon Carter exited Vanity Fair after 25 years at the helm and Robbie Myers left Elle after 17 years in the role.
