History Creator / NickJr

In October 2012, the Nick Jr. Channel began airing [=NickMom=], an adult-oriented programming block. This block aired in the nighttime hours, with new original shows and some syndicated repeats. The block's timing caused some controversy, as the Nick Jr. Channel only carried an Eastern Time Zone feed at the time, meaning that the block aired earlier in the day in some areas. A separate West Coast feed was eventually launched in February 2013, much to the relief of parents west of the Rockies. The [=NickMom=] block ran for almost three years, eventually shutting down on September 28, 2015, after an airing of ''Guarding Tess''.

In October 2012, the Nick Jr. Channel began airing [=NickMom=], an adult-oriented programming block. This block aired in the hours specifically targeted at mothers, with adult-targeted original programming and syndicated repeats. Despite this, some parents criticized the block for its coarse content. Time zones meant that the block aired earlier in some areas (since Nick Jr./[=NickMom=] carried only an Eastern Time Zone feed. Many of the more vulgar shows and the remixed ''Brady'' episodes bombed, with others getting content tweaks. A separate West Coast feed was finally launched in February 2013, much to the relief of parents west of the Rockies. By June 2013, the block consisted of some original programming mixed in with acquired sitcoms from Creator/NickAtNite. Eventually, [=NickMom=] was shut down on September 28, 2015, after an airing of ''Guarding Tess''.

On February 2, 2009, the Nick Jr. block was renamed to "Nickelodeon's Play Date", effectively (at the time) ending the 21-year history of Nick Jr. On September 28 of the same year, coinciding with Nickelodeon's rebranding and logo change, Nick Jr. became its own 24/7 channel, replacing Creator/{{Noggin}}. However, in 2014, the Nick Jr. name was brought back to the weekday-morning block on Nickelodeon; it continues to air, under the branding of "Nick Jr. on Nickelodeon" to distinguish it from the separate channel. Noggin itself would later be relaunched as a streaming service in 2015, serving as a separate brand operating concurrently with Nick Jr.

In October 2012, the Nick Jr. network began airing [=NickMom=], an adult-oriented programming block. This block aired in the hours specifically targeted at mothers, with raunchy original programming and syndicated repeats. This might not be so much the loss it seems, given that most of what aired in the late-night hours was just repeats of stuff that had aired during the day anyway. Despite this, angry parents loathed the block for its course content and the fact episodes of ''Series/TheBradyBunch'' had adult-themed ''Series/PopUpVideo'' commentary from Carol Brady. Worse, whatever was scheduled at 10pm in UsefulNotes/NewYorkState aired at 7pm in UsefulNotes/LosAngeles and 5pm in Honolulu [[note]]or 4, since Hawaii does not observe DST[[/note]] because of time zones, as at the time, Nick Jr./[=NickMom=] carried only an Eastern Time Zone feed.

On September 28, 2009, Nick Jr. became its own 24/7 channel. It replaced Creator/{{Noggin}}, which was eventually relaunched as a streaming service in 2015 and acts as a separate brand.

The Nick Jr. block is part of Nickelodeon's regular daytime schedule, typically running from 7 a.m./8 a.m. to 2 p.m. CST/3 p.m. EST. In its earliest days, the block was home to many classic off-network cartoons and foreign programming/{{anime}} such as ''WesternAnimation/TheWorldOfDavidTheGnome'', ''WesternAnimation/MuppetBabies'', ''Anime/BelleAndSebastian'' and ''WesternAnimation/{{Rupert}}''. The block was revamped in 1994, now with mostly Nickelodeon-made programming and a new host, Face. The block launched the pre-school juggernauts ''WesternAnimation/BluesClues'' and ''WesternAnimation/DoraTheExplorer'', while also airing some fondly-remembered anime such as ''Anime/TheNoozles'', ''The Adventure of The Little Koala'' and ''Grimm's Fairy Tale Classics''.

When Viacom merged with Creator/{{CBS}} in 2000, the existing ''CBS Kidshow'' Saturday-morning block, supplied by Creator/{{Nelvana}}, ended in favor of ''Nick Jr. on CBS'', complete with Face hosting (the only show to be held over from the old block was another Nelvana show, ''Franklin''). 2001 saw the block add programs from "normal" Nickelodeon, mostly programs to help stations meet the E/I quota, and it was renamed ''Nick on CBS'', at least until 2004 when it reverted to only Nick Jr. shows. The block on CBS ended in 2006 after the 13-year-long Viacom/CBS split.
