It was trying to be like Blue’s Clues. Nick Jr. aired the same episode all week. I think I saw an article that talked about why they did that with Blue’s Clues, can’t remember if it made it easier to learn when they got the same lesson all five days or if kids liked getting to rewatch the same episode all week.Makes me wonder what was the reason for airing the same Elmo's World segment on all five shows all week when the segment first started.
Obviously, five weeks later, somebody at Sesame Workshop decided to stop airing the same Elmo’s World all week long.
I guess you can also say that with the way they originally did it, it saved them from having to make a lot of new episodes in its first season. And maybe we would have still gotten ten episodes that season regardless.
