ComScore has just named a new management team, with Madison Avenue veteran and 360i founder Bryan Wiener named as CEO, MediaPost’s MediaDailyNews reports. Additionally, former GroupM digital chief Rob Norman was named to the company’s board.

“The moves follow a protracted period of disarray for comScore, which had been the dominant supplier of digital media audience ratings, but has lost steam and share — and some would say, market leadership — to Nielsen,” the story reports. “Wiener, who has served as executive chairman of 360i since turning the CEO role over to Sarah Hoftstetter, fills a CEO slot at comScore that has been vacant since Gian Fulgoni retired in November 2017.”

MediaPost adds: “In a related move, Bill Livek is moving from executive vice chairman and president of comScore to become vice chairman and a special advisor to Wiener.”

Current comScore board member Brent Rosenthal was named non-executive chair.

The report notes that the new roles become effective May 30.
