“Sesame Street” is an American institution. It began airing in 1969 as an educational program intended to help toddlers prepare for kindergarten. It has grown into a cultural staple and become one of the longest-running shows in TV history. Back in 2022, Laura Meckler learned that Season 55 of “Sesame Street,” which will start airing next year, will focus heavily on the emotional well-being of young kids. She spent almost two years following the cast and creatives behind the show as they researched, wrote, and filmed their upcoming season.  But as she was reporting, Laura learned that “Sesame Street” is in a fight for its own survival. Warner Bros. Discovery, which currently distributes “Sesame Street,” has announced that it will not renew the show’s contract for another term. Now, the iconic show is on the hunt for a new streaming partner and is preparing a major reimagining as it tries to adapt both to the needs of today's kids and to the increasingly competitive world of children’s TV. Today’s show was produced by Peter Bresnan. It was edited by Maggie Penman and mixed by Sam Bair. Subscribe to The Washington Post here.
