David Sarosi of Keith Olbermann’s old Countdown show on MSNBC has been named executive producer of Olbermann’s new Countdown on Current TV, which will premiere June 20. “Nobody knows what Countdown should be, more than Dave Sarosi,” said Olbermann, host of Countdown With Keith Olbermann and Chief News Officer at Current. For the past five years, Sarosi produced two key segments of the MSNBC show: the program “open,” which posed the question “Which of these stories will you be talking about tomorrow?” and the often-controversial Worst Persons in the World. Joining Sarosi as senior producers are Leslie Bella-Henry, Bob Lilly and Aaron Volkman.
