The final week of 2011, dubbed "Party Like It's the '90s", featured shows originally featured in the 1995 through 1999 incarnation of SNICK. KaBlam! and Animorphs were excluded and replaced with other SNICK programs of the era. This also included '90s Nick IDs. The December 31 edition, called "Stick Clark's New Year's Sticking Eve", featured the revival of "U-Dip," another Nick in the Afternoon feature, as an homage of the large list of objects dropped on New Year's Eve across the United States. Nickelodeon's trademark slime won the vote. The block started at 10 pm and ended at 2 am, with a re-air from 2 am–6 am, to accommodate the occasion.[9] To symbolize the end of 2011, the regular-length series finales of The Secret World of Alex Mack, Kenan & Kel, Clarissa Explains It All, and Doug aired from 10 pm to midnight.

To symbolize the beginning of 2012, the above-mentioned series premieres aired from 12 to 2 am. The night also featured Stickly's brother Woodknot and Face, who was the host of Nick Jr. for several years. It was, to date, the only appearance of any Nick Jr. property on the block until Face appeared again on March 27, 2016.[10]

On September 11, 2015, the block's Facebook page announced a new program block called "The Splat".[11] It was later confirmed that The Splat would launch on October 5, 2015, and run for eight hours. The same general format and program library is being used, with less repetition of series; whereas The '90s Are All That aired most of its shows five days a week, The Splat added a number of shows into the rotation that had either not yet been seen on the previous block or had only aired as special presentations, no longer airing them on a set weekly schedule. These programs also included programs that originally aired in the 1980s and the 2000s (decade).[7]

On March 27, 2016, in preparation for Easter, Face from Nick Jr. appeared on the block once again in a sketch where he attempts to help viewers find the Easter Bunny.[10]

On April 1, 2016, just minutes into a broadcast of CatDog, a random cutaway[12] occurred abruptly leading to the music video for "Never Gonna Give You Up" by Rick Astley featuring Stick Stickly in many scenes. This was dubbed "#StickRoll" and served as an April Fools' Day prank referencing Rickrolling, a form of internet pranking popular in the late 2000s. Later, during a broadcast[13] of Doug, the channel's aspect ratio was rotated 90 degrees as another joke.

On November 23, The Splat and Nick at Nite simulcasted a reunion special of Double Dare to celebrate the 30th anniversary of the show's premiere. The special featured the cast of All That participating in a new first-run episode of the game; to accommodate the simulcast, The Splat began airing an hour earlier than usual.[14]

To align itself with Nickelodeon's cross-platform branding, The Splat was renamed NickSplat on May 1, 2017.[8]

From November 17 to November 23, 2017, NickSplat aired every episode of Hey Arnold! every night. The marathon led up to the premiere of Hey Arnold!: The Jungle Movie, which was simulcast on Nickelodeon and Nicktoons. It was followed by the NickSplat premiere of The SpongeBob SquarePants Movie, making it the first time SpongeBob content has aired on the block.[15]

On January 22, 2018, The Ren & Stimpy Show began airing on the block at 3AM.[16]

On August 28, a NickSplat-branded channel was launched on VRV, featuring much of the same programming as well as debuting shows, such as Nick Arcade and Zoey 101.[17]

In January 2019, NickSplat briefly shifted to a marathon format where each night's programming consists solely of a block of one show. In addition, shows from the mid to late 2000s were featured on the first four Wednesday nights of January, starting with Invader Zim on January 2,[18] The Adventures of Jimmy Neutron: Boy Genius on January 9,[19] Danny Phantom on January 16,[20] and Back at the Barnyard on January 23.[21] The latter series marks the first time a show from the 2010s was broadcast in the block.

On March 15, 2019, NickSplat's YouTube channel was renamed NickRewind. Three days later on March 18, 2019, the rest of its social media along with the block was officially renamed "NickRewind".

In mid-July 2019, the NickRewind block was reduced for a brief time to two hours in the graveyard slot as Viacom attempted to introduce current-day archived content from AwesomenessTV and MTV to the network's schedule, which failed within days due to viewer feedback. It was re-expanded back into its full existing timeslot by mid-August 2019.

In September 2015, along with the announcement of The Splat, it was also announced that a new keyboard app would be released to the Apple App Store and Google Play, which is titled "The Splat Emoji Keyboard" developed by Snaps Media. The keyboard features pictures and GIFs of 90s Nicktoons characters and various objects. The app was released in October 2015, coinciding with the launch of The Splat.[23]

On May 2, 2017, the app was renamed "NickSplat Keyboard" to coincide with the name change of the block; despite the current name change, the former name remains.

In 2011, when the block was known as "The '90s Are All That", it had its dedicated website, which featured clips, the schedule, and voting sections.[24] In 2014 when the block re-branded, the website was removed and was simply a webpage on TeenNick.com. When The Splat was announced, a new website was made and featured quizzes, clips, and posts from their various social media pages until its shutdown as its next name as NickSplat in late February 2018.

In 2017, NickSplat launched a weekly Web series, NSFW: Nick Shows were Freakin' Weird, which features clips of NickSplat shows containing adult innuendos that viewers would not have understood as children.

In 2016, Nickelodeon UK launched a UK version of "NickSplat". Instead of it being a block, it's an online only service on Nick.co.uk.[25] For a limited time in 2017, Nicktoons UK broadcast some of the shows from the block.

In December 12, 2016, Nickelodeon Netherlands & Flanders launched a Dutch version of "NickSplat" simply called "Splat". The block airs on weeknights at midnight since the channel was extended to 24/7 programming.[26][27][28]

In August 2020, Nickelodeon (Latin America) launched a localised version of "NickRewind" airing older Nickelodeon shows from the 90s to the 2010s, it was only aired during a month long.

A NickRewind branded channel is avaliable on Pluto TV since August 3, 2020.
