The chief executives of Time Inc.’s magazine and book divisions will swap jobs in a move intended to “reinvigorate” both units, Time Chief Executive J. Richard Munro said in New York. Kelso F. Sutton, 47, chief executive of Time’s magazine group, will become chief executive of the book publishing unit, and Reginald K. Brack Jr., 49, present head of the books unit, will take Sutton’s job.

The swap, which is effective immediately, “is a reinvigorating experience that will enable both groups to enjoy fresh perspectives,” Munro said.
