Comscore CEO retiring as Nielsen rival gets big chance and more competition: Bill Livek announces departure amid growing industry interest in Nielsen competitors.

Livek became CEO in November 2019, replacing interim CEO Dale Fuller, who served for seven months following the abrupt departures of former CEO Bryan Wiener and President Sarah Hofstetter earlier that year (they later joined e-commerce analytics firm Profitero).
