This is a list of television programs broadcast by Nickelodeon in the United States. The channel was first tested on December 1, 1977, as an experimental local channel in Columbus, Ohio. On April 1, 1979, the channel expanded into a national network named Nickelodeon. The first program broadcast on Nickelodeon was Pinwheel, a preschool series created by Dr. Vivian Horner, who also conceived the idea for the channel itself. At its launch, Nickelodeon was commercial-free and mainly featured educational shows. By 1984, the channel began accepting traditional commercials and introduced more entertainment-focused programming. In January 1988, the network launched a weekday morning block for preschoolers called Nick Jr., which carried Pinwheel and other educational series. Around the same time, Nickelodeon began investing in original animated shows, which premiered in 1991 under the "Nicktoons" branding. Since then, the channel has consistently aired a mix of original live-action and animated titles.
