Nick Jr. (sometimes disambiguated as Nick Jr. on Nickelodeon or Nick Jr. on Nick, and sometimes referred to as Nick, Jr.) is an American morning programming block that airs on Nickelodeon every weekday. It was launched on January 4, 1988. Nick Jr. features a lineup of shows aimed at children aged 2 through 8.
In 2009, Nickelodeon launched a separate channel named after the Nick Jr. block as a replacement for the original Noggin cable channel. The channel is known on air as the "Nick Jr. Channel" to differentiate the two services.
