HBO on Tuesday announced a January 16 debut for Sesame Street, its new series that uses one monster-overrun city block to explore the importance of shapes and numbers.

The first two episodes of the 46th season of the PBS import will air Saturday, January 16 at 9 and 9:30 a.m. New episodes will then air every Saturday at 9 a.m., followed by an encore at 9:30. Spanish-dubbed new episodes will simultaneously air on HBO Latino. Episodes will also be available on HBO NOW, HBO GO, and HBO On Demand, as well as HBO Family.

Other changes to the children's TV stalwart include a half-hour format, a new cast member named Nina, and new opening and closing songs.

Sesame Street will now premiere new episodes on HBO

Old episodes of Sesame Street will continue to air weekdays and Sundays on PBS KIDS and local affiliates. Season 46 will begin airing on PBS KIDS next fall. HBO announced its deal to premiere the next five seasons of Sesame Street this summer. The show was previously on public broadcasting since its genesis in 1969.
