All programming during the block, as is standard for Saturday morning network programming, was labelled as meeting E/I requirements, as tennous as some of the claims of educational content may have been. This is part of the reason why some of Nickelodeon's most popular programs (most notably "SpongeBob SquarePants" and "The Fairly OddParents") did not appear on the block, even during the more open-formatted "Nick on CBS" era.
