Nick Jr. is a morning preschool programming block that airs on Nickelodeon every weekday. Launched on January 4, 1988, it features programming aimed at children aged 2 to 8. Since its launch on April 1, 1979 and throughout the 1980s, the network aired programs for preschoolers (most prominently Pinwheel and Today's Special) on weekdays 8:00 am – 2:00 pm and weekend mornings. A new rebrand for the block that abbreviated its name to Nick Jr was gradually rolled out from September 5, 1988 to the summer of 1989.
