In 1988, KCIK was purchased by New York entrepreneur Jack Mulderrig Sr., who invested in the construction of a new studio facility at 6004 North Mesa Street in the northwestern part of the city which opened in June 1994. On January 3, six months before the opening of the new studios, the station changed its call letters to KFOX-TV, to reflect its network affiliation and mark it as one of Fox's 10 strongest affiliates. The use of the KFOX-TV callsign differs from other stations that incorporate the network name into their call letters—ABC, NBC and CBS each have owned-and-operated stations in New York City and Los Angeles that bear their associated network within their calls; however, the KFOX calls were not used by Fox for its O&O in Los Angeles (which retained the KTTV calls it had prior to former parent Metromedia's 1986 purchase by the network's original parent company News Corporation; a similar situation later arose with WFOX-TV in Jacksonville, Florida (which is still owned by Cox) in 2014, when it took on those call letters as they were not already used by Fox's New York City O&O, which uses its legacy WNYW callsign).
