Fox affiliation
After Sam Zell took over control of the Tribune Company in December 2007,[34] he reevaluated many aspects of the company. He learned that, under prior management, Tribune had been offered the Fox affiliation for KSWB-TV and turned the network down. McKinnon Broadcasting, owner of KUSI-TV, had also been talking to Fox about moving its affiliation. In mid-March 2008, he told Chicago Tribune columnist Phil Rosenthal that when he heard about this, "I called Rupert [Murdoch], and I said, 'Rupert, what the [bad word] is going on?' ... He says, 'Well, why didn't you take it when we offered it in the first place?' I said, 'Well, you didn't call me. You called those [less bad word].[35]
On March 23, 2008, TelevisionWeek reported KSWB-TV would switch to Fox, which was then confirmed to be effective August 1.[36] Fox's executive vice president of network distribution, Jon Hookstratten, cited the fact that, as a Mexican station, XETV—an original Fox affiliate from the network's creation in 1986[37]—had to answer to a different communications regulator as one reason for the changeover. The switch gave Tribune a seventh station airing Fox programming, solidifying its status as the second-largest Fox affiliate owner.[38] The news left the fate of XETV uncertain. That station's management originally contended their Fox affiliation agreement ran through 2010. On July 2, Bay City Television/Grupo Televisa signed an affiliation agreement to bring The CW's programming to XETV. With the Fox affiliation agreement, KSWB-TV's ten-year contract with The CW was rendered void, and KSWB-TV and XETV exchanged affiliations on August 1, 2008.[39][40] The switch was met with an open letter from XETV management ruing Fox's behavior toward their station, stating in part, "Unfortunately, in these troubled times, it seems as though there is no honor or loyalty anymore."
The Fox affiliation deal kickstarted the return of in-house local news production to KSWB-TV, with Tribune initially stating it aimed to produce three to four hours a day of local news. Tribune tapped Rich Goldner, news director at KTLA, to move south to San Diego and set up a newsroom at KSWB-TV.[41] Upon the affiliation switch, KSWB-TV debuted a new weekday morning news program (initially airing from 5 to 9 a.m. and hosted by Arthel Neville) and an hour-long 10 p.m. newscast, both produced in high definition.[42][43] A total of 50 staffers were added to KSWB to support the new news operation.[44] By 2014, KSWB-TV aired weekday local newscasts in the morning and at 1, 4, 5, 6, and 10 p.m.[45]
In 2017, Sinclair Broadcast Group announced it had agreed to purchase Tribune Media for $3.9 billion (equivalent to $ in ).[46][47] As part of divestitures associated with the deal, KSWB-TV and other stations were to be sold to Fox Television Stations.[48] Both transactions were nullified on August 9, 2018, when Tribune Media terminated the Sinclair deal and filed a breach of contract lawsuit;[49] this followed a public rejection of the merger by FCC chairman Ajit Pai[50] and the commission voting to put the transactions up for a formal hearing.[51]
Following the merger's collapse, Nexstar Media Group announced a $6.4 billion (equivalent to $ in ) all-cash purchase of Tribune Media on December 3, 2018.[52][53] The sale was completed on September 19, 2019.[54] A 7 p.m. newscast was added in 2020 and extended to an hour the next year. By 2022, KSWB was producing 64 1/2 hours of local news and sports programming a week, as well as a daily lifestyle show with paid segments, The Localist SD,[55] and simulcasts of 11 regular-season games of the Los Angeles Clippers basketball team from KTLA.[56]
On May 8, 2023, Nexstar announced that it would acquire KUSI-TV from McKinnon Broadcasting for $35 million (equivalent to $ in ) with the intention of making it an affiliate of The CW when the affiliation becomes available.[57] The deal was completed on August 31.[58] In 2025, Nexstar applied to acquire Tegna Inc., owner of San Diego CBS affiliate KFMB-TV;[59] the purchase received FCC approval on March 19, 2026,[60] and closed the same day.[61]
