That is amazing! However, based on the subject line, I was led to believe that "Sesame Street" will no longer be airing on television. But the idea of putting the show on a streaming service is a wonderful idea, as there would be broader access to the show via computers or mobile devices.
The classic episodes as an on-demand basis is also incredible news too. However, I don't know if some animated inserts will be edited out for the on-demand service. I would expect those episodes will be edited for the purpose of adding the full Friday closing credits.
Either way, HBO Max will be Sesame Street paradise next spring.
