The move took place earlier this month. For now, Mr. Glock, 51, is on special assignment to Richard Hughes, vice president of global purchases, until September 30.
The shift occurs a month after P&G said it would combine its brand development and marketing and media operations under the leadership of Marc Pritchard, head of global brand building.
Ms. Howell, 46, under the new title of vice president of global media and brand operations, also will be responsible for developing global best practices for media, communications planning, branded entertainment, talent management, and sports and event marketing. She will report to Mr. Pritchard.
Mr. Atkinson, 52, will take over global communications with media and PR firms in addition to his marketing responsibilities. He will report to Hughes and Pritchard,
