El Tigre Rugrats

Programs currently broadcast
This is a list of television programs formerly, currently, or soon to be broadcast by Nicktoons.

Nicktoons airs or had aired many Nickelodeon-produced animated series that premiered on Nickelodeon. Nicktoons has also shown some non-Nicktoons produced by Steven Spielberg for Warner Bros. Animation, which Nickelodeon had rights to at the time the network was launched, and international shows such as Corneil and Bernie, Martin Mystery, and various Nelvana, Teletoon, and CBBC fare.

Nicktoons also takes off a few "library" shows that are also in heavy rotation on other MTV Networks outlets or to rest them from viewer rot. The Ren and Stimpy Show was taken off the network after it had started airing on Spike TV, but returned around July 30, 2005. Nicktoons Network used to air a Short Break or a Film Festival Short Break at the end of every half-hour. However, this time is now used to run more promotional material.

Programs Formerly broadcast

 * Shorts from KaBlam! (e.g. Sniz & Fondue, Life With Loopy, Action Leage Now!, and Prometheus and Bob were the most seen on the Short Break from 2003-2008.

Origin and launch
On October 2, 2007, The CW announced due to a joint decision between the network's parent companies Time Warner and CBS Corporation that it would discontinue the Kids' WB programming block, due to the effects of children's advertising limits and competition from cable television, and sell the programming time to Grupo Clarin (through its subsidiary 4Kids Entertainment). Kids' WB ended its run on The CW on May 17, 2008 (Kids' WB, like The WB Television Network that the block originated, then relaunched as an online-only video on demand service). 4Kids Entertainment took over programming the block on May 24, 2008, premiering under the name The CW4Kids. In addition to programming the block, 4Kids also handled responsibilities for its content and advertising revenue.

At the time of the block's launch, 4Kids also programmed the competing 4Kids TV block for Fox, until that network nullified its time leasing agreement with 4KidsTV on December 27, 2008, due to a dispute between Fox and 4Kids involving 4Kids' failure to pay the network for its time lease, and the network's inability to maintain guaranteed clearances for the block, due to difficulties getting Fox affiliates and stations that would be used as default carriers of the block in markets where the Fox station did not carry 4Kids TV to air it. The CW4Kids was not renamed in order to avert confusion and due to contractual obligations to feature the CW name in some form within the block's title.

On April 27, 2010, 4Kids announced the rebranding of The CW4Kids under the new name Toonzai, a name change that took effect on August 14, 2010.

Takeover by Saban Brands and end of Toonzai
On June 26, 2012, Kidsco Media Ventures, an affiliate of Saban Capital Group, finalized a bid to acquire 4Kids' agreement with The CW for the block. On July 2, 2012, it was announced that Saban Brands, via Kidsco Media Ventures, began programming the block, which would be relaunched under the name Vortexx. Toonzai quietly ended its run on The CW on August 18, 2012, after a Yu-Gi-Oh! marathon, with Vortexx premiering the following week on August 25, 2012. Some of Toonzai's programming, including Yu-Gi-Oh!, Yu-Gi-Oh! Zexal, Sonic X, and Dragon Ball Z Kai continued to air on the block until September 27, 2014, when Vortexx ended its run.

Programming differences
In most markets, CW affiliates used the network's recommended Saturday morning scheduling for the block – though some such as CW owned-and-operated station WUPA in Atlanta aired it on Sunday, instead due to regular Saturday programming. Connecticut affiliate WCCT-TV aired three hours on Saturday, and two hours on Sunday. KMAX-TV in Sacramento, California aired the entire lineup, but it had a four-hour tape delay, running from 11:00 a.m. to 4:00 p.m. WLFL in Raleigh, North Carolina and WNUV in Baltimore, aired the entire lineup, but it had two hours earlier, running from 5:00 a.m. to 10:00 a.m. San Diego's XETV-TV, aired three hours from 5:00 a.m. to 8:00 a.m. and two hours from 10:00 a.m. to Noon. San Antonio's KMYS, which affiliated with The CW in 2010, aired it on Sunday and Monday before 5:00 a.m. Other stations preempted portions of the block; Shreveport, Louisiana's KPXJ-TV preempted the final hour of the block. Columbus, Georgia's WLTZ-DT2 preempted the first half-hour of the block.

While The CW recommended that its affiliates carry The CW4Kids/Toonzai block at 7:00 a.m. to Noon Saturday mornings (regardless of time zone), its secondary CW Plus national feed for smaller markets aired the Toonzai block an hour earlier on its broadcast and cable-only affiliates in the Central, Mountain and Alaska time zones, as The CW Plus operates two separate feeds running on Eastern and Pacific time zone schedules.
