2002. Fox ended its network-supplied children's programming on December 28, 2008, amid a dispute over monetary compensation and affiliate clearance for the block's time-lease agreement. (4KidsTV was replaced on January 3, 2009, with the paid programming block Weekend Marketplace until Fox brought back children's programming with the launch of Xploration Station on September 13, 2014.) Channel 27's programming lineup during this period had become a more traditional format for an independent station, with a mix of classic off-network sitcoms, syndicated talk and reality shows, movies as well as children's programs sourced from Fox Kids. In December 1999, four months after the FCC began permitting television station duopolies, Fox Television Stations purchased KDFI from Dallas Media Investors for $6.2 million, creating a legal duopoly with KDFW. The sale received FCC approval on February 18, 2000. The acquisition resulted in the KDFW/KDFI combination becoming the first television duopoly in the Metroplex and the first duopoly that Fox operated as a whole (predating the group's acquisition of Chris-Craft/United Television's UPN-affiliated stations on August 12 of that year).

On that date, The CW also signed a ten-year affiliation agreement with Tribune Broadcasting, under which sixteen of the group's eighteen WB-affiliated stations – including KDAF, which Tribune acquired as part of its July 1996 acquisition of Renaissance Broadcasting – would serve as the network's charter stations. In response to having its UPN affiliates be passed over for affiliations with The CW, Fox Television Stations stripped all network branding from and ceased promoting the network's programming on its UPN-affiliated stations. However, it is very unlikely that KDFI would have been selected as The CW's Metroplex area affiliate in any event. Representatives for The CW were on record as preferring to align with UPN and The WB's "strongest" affiliates; KDAF had been ahead of KDFI in the ratings since shortly after channel 33 became the market's original Fox owned-and-operated station in October 1986. Nearly one month after the CW launch announcement, on February 22, 2006, Fox Television Stations and fellow News Corporation subsidiary Twentieth Television announced the launch of MyNetworkTV, a network created primarily to
