Following his retirement on 31 January, Fulgoni (pictured) will take on an advisory chairman emeritus role. He will provide advisory services to the measurement firm until January 2019.

Fulgoni has held the position of chief executive since August 2016. He co-founded the company in 1999, serving as executive chairman of the board from 1999 until 2014, and as chairman emeritus from 2014 until 2016.

The company has yet to appoint a replacement for Fulgoni. A committee chaired by comScore’s board chair Sue Riley will direct the search for candidates for the chief executive role.

Riley said: "ComScore has become an industry leader and a trusted partner, and Gian’s leadership has been instrumental in making the company what it is today. I look forward to continuing to work with Gian to ensure a smooth transition as we look to identify a CEO who will take the company to the next level.”
