Background: This was a kids channel formed by RKO Pictures, during 2003-2007, it was renamed RKO 4 Kids. But when RKO Pictures, almost lost money from the rebranding, it was reverted back to RKO Kids.
Logo: On a dance floor, we see a cartoonish version of the RKO tower dancing on the floor, a few seconds later, it jumps and becomes a still 2D image, the the text "RKO 4 Kids" in a childish font appears (The "4" is backwards) below the tower.
FX/SFX: Good animation from The Line Animation.
Music/Sounds: A jazzy theme that plays throughout the logo.
Availability: Extinct. Was seen during the rebranding.
Scare Factor: None. This is well known animation fitting for the 2000s. But compared to the next id, IT'S NOTHING!
(March 26, 2007)
Logo: We see the same concept from the previous logo, but before it can finish dancing, an open-hand slaps the logo, then a mouth appears and eats the tower, then it transforms into the RKO Kids logo from 2007-present, with the whole text being covered in spray can graffiti.
FX/SFX: Same as the previous logo.
Music/Sounds: The same music from before, but it stops when a slapping sound appears. along with an 7-note heavy metal theme, and a biting noise when the mouth eats the tower.
Availability: Extinct. Appeared when the name was reverted back to "RKO Kids".
Scare Factor: High to Nightmare. The destruction of the RKO 4 Kids logo, and the crazy animation can give people nightmares, this would also annoy fans of the previous id if they weren't expecting the previous id.
Logo: Here are the variants:
Before TV-Y7 Shows: We see 2 10-year old rappers dancing, then the RKO Kids logo appears after 6 seconds.
Before TV-Y Shows: We see a 5-year old kid watching cartoons on TV, he then says "What a good day watching Saturday morning cartoons.", then the RKO Kids logo appears.
FX/SFX: See above.
Music/Sounds: Each has it's own theme depending on the id.
Scare Factor: None, it's too way better than the previous id.
