On March 3rd, 1999 Nick begins showing re-typed credits on the left side of the screen with the show's logo on top, while showing promos on the right side and using older Nickelodeon logos that wasn't being used on TV with copyright notice at the bottom while the show's end theme was playing.
Cloud 2 (Used on CatDog, Rugrats, Speed Racer and SpongeBob SquarePants)
Amoeba (Used on Doug and The Wild Thornberrys)
Baroque (Used on Hey Arnold!)

Evolution (Used on SpongeBob SquarePants)
Flower (Used on All Grown Up, Avatar, Catscratch, Rocket Power, Rugrats and SpongeBob SquarePants)
Radishes (Used on The Amanda Show, The Fairly OddParents, Rugrats and SpongeBob SquarePants), there's variants with faint cut off.
Same as the 2001 version but with the TRP (Tollin/Robbins Productions) It uses The Amanda Show version the with the it uses a faint cut off version the Light Bulb buzzing sound.
This was for going into a commercial but the other is behind a teal background with The Fairly OddParents instrumental theme playing and copyright notice.
When Nick Jr. Productions is merged. Nickelodeon made new "light blub logo", First, the splat is shown with a black background. Then it shines orange to red. The splat changes shape to an light blub. You could hear the kids laughing. Then the light blub reverts back to the splat. The background turned black except for the right side. The version could have bylineless or having a copyright disclaimer. Sometimes the logo could have the faster version. First, The light blub changed shape to the splat. There's no kids laughing here. The splat is on the downish right. The splat is small at the end. The faster version could be seen on the Backyardagains. The normal ones could appear over Nick Jr. or Nickelodeon shows.
This article or section lacks a former logo at the moment. You can help Logopedia by uploading it here.
