In 2001, Fox Television Stations acquired several UPN affiliates owned by Chris-Craft Industries through its BHC Communications station group, effectively creating a duopoly between KTTV and KCOP-TV (channel 13). That fall, channel 11 dropped the Fox Kids weekday block and moved it to KCOP; Fox Kids discontinued its weekday block altogether in January 2002, with the lineup left now airing only on Saturday mornings under the new "Fox Box" branding (which was replaced by 4Kids TV in September 2002), KTTV began to air Fox's children's programming once again. Since the 4Kids block was replaced by Fox with the infomercial block "Weekend Marketplace" in December 2008, the station now airs five hours of educational programming, two more than required under FCC guidelines, as "Xploration Station" replaced "Weekend Marketplace", which moved to KCOP, in September 2014.
