NickRewind is a programming block on TeenNick that airs Nickelodeon shows from the 1980's, 1990's and 2000’s. It began in 2011 as The 90's Are All That, and was re-branded as The Splat on October 5, 2015, NickSplat on May 1, 2017, and finally NickRewind on March 18, 2019.
The Ren & Stimpy Show currently reruns on the block. For some strange reason, the show is rated TV-G on NickRewind, despite it being rated TV-Y7 on Nickelodeon.
The Ren & Stimpy Show had regularly aired during the 90's Are All That era from 2011 to 2012, and was not seen afterwards outside of special events. It would later return during the era of The Splat, only for it to be taken off. Reruns of Ren's Toothache and Rubber Nipple Salesmen played in August 2017; other reruns, however, were not scheduled until January 22, 2018, where the series returned to the block, airing every night at 3:00 AM until sometime in April 2018. The series returned to the line-up on February 25, 2019 before leaving on July 14, 2019. It later returned on January 7th, 2020, with timeslots now at 4:00 and 4:30 AM.
