UPN Kids was a short-lived weekday and Sunday morning children's programming block on UPN that launched on September 10, 1995. During the 1998-1999 season, the block was called The UPN Kids Action Zone. The block aired for 2 hours each day (7:00AM–9:00AM on weekdays and 9:00AM–11:00AM on Sundays). UPN Kids shut down on September 5, 1999 and was replaced with Disney's One Too.
When UPN launched in 1995, it aired cartoons Space Strikers and Teknoman on weekends; the lineup was known as UPN Kids.
In 1997, UPN went a different way with its children's program block by airing new episodes as well as reruns of the syndicated Sweet Valley High and a new series, Breaker High on weekdays and Sundays aiming the programs at teenagers.
In January 1998, UPN began talks with The Walt Disney Company to run a daily two-hour Disney kids block but the talks with Disney were called off a week later do to a dispute over branding the block and deciding how much E/I programming Disney would provide, UPN then began talks with Nickelodeon. At which time UPN made a deal with Saban Entertainment to program the block on Sunday mornings and air shows like The Incredible Hulk, X-Men, Spider-Man and Big Bad Beetleborgs.
