Disney's One Too was a spinoff of Disney's One Saturday Morning, and resembled The Disney Afternoon. In the summer of 1999, UPN and Disney began a programming alliance where UPN would air two hours of Disney children's programming during its kids block on Sunday mornings and weekday afternoons. Originally announced as "Whomptastic," the block debuted on September 5, 1999 six-days-a-week as a companion to Disney's One Saturday Morning franchise on ABC. Hercules is the only series to transition from Disney Afternoon to Disney's One Two. On Wekkedays, it was 3pm to 5pm and on Sundays, it was 7am to 9am or any other time depending on the local channel.
September 5, 1999–February 6, 2000 had: Hercules: The Animated Series (1998-1999), Disney's Doug (1996-1999), Sabrina: The Animated Series (1999-2000) and Disney's Recess (1997-2003).
February 7, 2000-October 1, 2000 had: Disney's Doug (1996-1999), Sabrina: The Animated Series (1999-2000), Pepper Ann (1997-2001) and Disney's Recess (1997-2003).
October 2, 2000–September 2, 2001, Pepper Ann was moved to 3pm and Sabrina: The Animated Series stayed at 3:30 and the new Buzz Lightyear of Star Command (2000-2001) that aired on UPN took the 4pm slot and Recess stayed at 4:30pm.
From September 3, 2001-September 1, 2002, Sabrina moved to 3pm, Recess moved to 3:30 and The Legend of Tarzan (2001-2003) took 4:30, while Buzz Lightyear stayed at 4pm. The Weekenders aired on Sunday, being the first show of the block, taking Sabrina's place.
From September 2, 2002-August 29, 2003, Digimon Frontier took the 4pm slot. Buzz was first, followed by Recess and Digimon was followed by Tarzan. Recess had six seasons and 128 episodes. Sabrina the Teenage Witch returned to syndication years later through DiC.

On September 14, 2002, Disney's One Saturday Morning was terminated and rebranded as ABC Kids. ABC Kids' block is now completely reruns from the Disney Channel, except for the Power Rangers, which now only airs on ABC. In the summer of 2003, Disney's One Two block completely ended. NBC became the first network to drop children's programming entirely in 1992, when it was replaced by the live-action teen programming block called TNBC ("Saved by the Bell"). The WB and UPN merged to form The CW in 2006, leaving The CW to air the Kids' WB block up until 2008, when became The CW4Kids. However, some Fox affiliates aired the 4KidsTV starting in 2002 and it was dropped the Fox Box/4KidsTV block entirely in 2008 as the block became CW4Kids. Now, only NBC (which started again in 2002), CBS, ABC, and theCW air children's programming on Saturdays. FOX and MyNetworkTV do not.
