The Boston Globe's editor, Brian McGrory, will step down in the coming months after 10 years at the helm.

Linda Henry, The Globe's chief executive, told the newsroom that Mr. McGrory will stay on until the end of the year or when a successor is found. Mr. McGrory will be writing an opinion column for The Globe.

Our deep commitment to original reporting, produced by a global staff of over 1,700 journalists, makes stories like this possible. The work can only be done thanks to the support of our subscribers. We would like to see you become one today.

The Globe is looking for a new editor.

Ms. Henry wrote in the memo that Brian has been a vital part of the leadership for the past decade.

She said that he gave the Globe the greatest advantage that a media organization can have: high journalistic standards, an innovative mind-set, and a deep commitment to the communities that they serve.

Mr. McGrory said that being editor of The Globe was one of the best jobs in the city and that it was time to move on.

He said that the Globe will benefit from the fresh perspectives of a new editor.

Mr. McGrory was a paperboy for The Globe when he joined the newsroom in 1989. He was named the top editor in December 2012 after Marty Baron left to work for The Washington Post.

The New York Times Company bought The Globe and other properties in 1993 for more than one billion dollars. John W. Henry bought them from the Times for $70 million.

The Globe's newsroom won three Pulitzer Prizes. As print circulation continued to decline, it focused on increasing its digital offerings.

The Globe is considered to be the most successful regional news organization in the country. The Globe has more than 200,000 paying digital subscribers.
