Well, tomorrow is very important day in the history of children's programming, the major network's (ex: Fox, CW, ABC) traditional children's programming blocks comes to a end as Vortexx (The final programming block that exists) is airing for the last time on The CW, and will be replaced with... an educational and informational block... that's owned by Litton Entertainment (And will be their THIRD E/I BLOCK!).
Thanks to the likes of FCC Mandates, all local major networks are required to air at least three hours of educational and informational shows each week. This decision made the major networks either add E/I shows to their children's block's line up, retool, or cancel them. Cable Networks also likely played a part in this, as they have channels aimed to children that air every day, and are not required to air any E/I shows.
This is sad as I, and many others, grew up with Saturday morning programming blocks, like Fox Kids, Kid's WB, and One Saturday Morning, and have many memories of waking up early on Saturday just to watch a new episode of Power Rangers, Digimon, Sonic X, Recess, and many others. Despite these blocks coming to an end, their legacy will live on thanks to the likes of VHS tapes and video streaming websites, like Youtube, and our memories.
