teen-oriented sitcoms Lizzie McGuire and Even Stevens (both originated on Disney Channel as part of what would be a gradual takeover of ABC's Saturday morning lineup by the cable channel's programming), while Viacom-owned CBS aired E/I compliant preschool programming from Nick Jr., and NBC was airing teen-oriented sitcoms (later to be replaced the following year by E/I-compliant programming sourced from Discovery Kids), splintering the audience. The added factor of Nickelodeon's aggressive schedule that outrated all of the broadcast networks among children on Saturday mornings left Fox Kids behind, and the programmers could find no way to catch up and stand out in this crowded field. Fox Family, despite good reviews, had a 35% audience decline, which led to the stake in Fox Kids Europe and Fox Family Worldwide (along with Saban Entertainment) being sold to The Walt Disney Company in 2001. After Fox Family Worldwide was sold to The Walt Disney Company in July 2001, Fox Kids was placed under the oversight of Fox Television Entertainment and moved its programming operations to Fox's headquarters on the 20th Century Fox studio lot; Fox discontinued daytime children's programming in December 2001, giving the time back to its affiliates.
