'Sesame Street' CEO Apologizes for 'Misunderstandings' About Cast Changes

"We certainly could have done a better job of communicating," he wrote.

"We apologize for the misunderstandings around the changing cast roles at Sesame Street," Dunn wrote. "Over more than 40 seasons, Bob McGrath, Emilio Delgado and Roscoe Orman have made enormous contributions to both television and to the lives of preschoolers. They are, and always will be, a key part of the Sesame family."

A statement last week from Sesame Workshop said the three veteran actors would "continue to represent us at public events," but fans still took to social media to voice their concerns.

Dunn's post continued, "As always, our curriculum and educational goals drive our story lines and character appearances. These change season-to-season. In 2014, when we first began producing the current half-hour show format, we let all of our cast members know of the shorter story lines and, therefore, reduced appearances."

This season, he added, the stories did not include the three actors, and "we certainly could have done a better job of communicating with them about our ongoing episode plans."
