Mark Golin, group editor at Time Inc.’s style & entertainment group, and Larry Hackett, editor of People for the past eight years, are leaving the magazine company as it prepares for this year’s split from Time Warner.

David Geithner, SEG’s executive VP, and Norman Pearlstine, chief content officer, disclosed the departures via a staff memo today.

Golin joined Time Inc. from AOL 11 years. As editor of PEOPLE.com, he orchestrated its growth and expansion across mobile, video and social platforms. He is staying out during a transition period to help integrate print and digital editorial.

Hackett, in the memo, is praised for in “commitment to respected journalism, creative insights and brand acumen.” He helped stabilized magazine “during a time of unprecedented competition.” Hackett “launched new franchises including world’s most beautiful woman and teacher of the year.”

Jess Cagle, editor of Entertainment Weekly, is the new PEOPLE and PEOPLE.com editor. He’ll double as EW’s editorial director. His EW editor successor will be announced shortly. Cagle began his Time Inc. career in 1987 as a reporter for PEOPLE. Hackett will remain at Time Inc. for several weeks to assist Cagle during the change-over.
