The original logo for what was then known as Nicktoons TV, featured orange silhouettes of Nickelodeon characters (a silhouette of SpongeBob SquarePants is seen in this logo) with the then-logotype for Nickelodeon printed within the silhouette as "Nick" and the "Toons TV" lettering underneath.
Nicktoons (first era)
On September 13, 2004, the channel was renamed Nicktoons. This change was believed to be the golden years of Nicktoons by fans due to the channel featuring many classic Nickelodeon programming on it during its time and the logo being a homage on the original Nickelodeon logo.This logo might be representing spit.
On September 5, 2005, Nicktoons introduced a new look and became Nicktoons Network. The logo was designed in house. Exopolis created the new on-air package. This logo has a globe shown with orange slime on it. Beginning with this era, Nicktoons would begin to feature both classic and original programming. On September 28, 2009, Nicktoons Network was reverted back to Nicktoons with a new logo to catch up with Nickelodeon.
Nicktoons (second era)
As part of Nickelodeon's rebranding effort, all of its channels were rebranded on September 28, 2009. Along with the rebrand, Nicktoons Network reverted back to its old name used from 2003 to 2005. The "TOONS" part is show in red, blue, silver/grey, yellow and green in bumpers and promotional advertisements and even on on-screen bugs in 2009-2014. This red one is still sometimes used in Nicktoons bumpers and advertisements.
On May 5, 2014, the main variant and on-screen bug for "TOONS" was changed. While multiple other designs for the Nicktoons logo remained on bumpers and sometimes on-screen bugs, this lime logo replaced the red one as the main variant.
In 2016, Nicktoons replaced the green 'toons' screen bug to blue again.
