I've noticed that lately, they haven't really been uploading much on the official YouTube channel, except for the Throwback Thursday clip (which is practically all I care about). I've noticed they really haven't uploaded much from Season 46. I remember they originally uploaded all of 4601 and 4602 but they got taken down. Last week they also uploaded that "S is for Safari" film but shortly took it down after. I wonder if maybe HBO is forcing this, because I think they now want to be the official place for Sesame Street.
