KMSB is a Fox-affiliated television station that is licensed to Tucson, Arizona. Owned by Sander Media, LLC and operated by Raycom Media through a shared services agreement with CBS affiliate KOLD-TV, it is a sister to MyNetworkTV affiliate KTTU. It broadcasts an ATSC digital signal on UHF channel 25 (remapped to virtual channel 11.1 via PSIP) from a transmitter located atop Mount Bigelow; as a result of the transmitter's location, residents in the northern part of Tucson, Oro Valley and Marana cannot receive adequate reception of the station. Its studios are located with KOLD-TV on North Business Park Drive on the northwest side of Tucson, near the Casas Adobes neighborhood.

Tucson gained its first independent station when KZAZ signed on the air February 1, 1967.[1] It was licensed to Nogales, but had its main studios in Tucson.[2] The station aired movies in both English and Spanish, dramas, sitcoms, bull fights, cartoons and other general entertainment fare. It had a local news department and newscast.

The station was owned and operated by out of town investors, including [3] The sales manager, Hank Lominac, hosted the prime time movies. The sports anchor, Bill Roemer, anchored live sports from the University of Arizona. The hour-long newscast at 9 p.m. was anchored by former KOLD news director George Borozan and co-starred John Scott Ulm. It featured long interview segments, and its field reports were captured on one field camera/recorder.

In 1978, KZAZ bought a satellite downlink and started carrying the first half-hour of WPIX/New York's newscast, which was rebranded as Independent Network News. Borozan was cut to a half hour and either followed or led into (at various times) the INN report, which was tape delayed.

In 1984, the station was sold to Mountain States Broadcasting, a division of the Providence Journal Company, who changed the call letters to KMSB-TV on September 12, 1985. To cut costs, Providence Journal axed the station's news broadcasts once it took over. The station became a charter Fox affiliate when the network signed on October 9, 1986, and has been affiliated with Fox longer than any other station in Arizona.

In the early 1990s, KMSB began operating KTTU, which had been owned by Clear Channel Communications, and was allowed to move its city of license from Nogales to Tucson in 1991. Belo Corp. became the owner of KMSB after the company purchased Providence Journal's holdings in 1997.

KMSB retired from cartoons at the same time; 4Kids TV aired on KTTU until its shutdown on December 27, 2008, and stills airs Fox's new Saturday morning block, Weekend Marketplace.

In November 2011, Belo announced that it would enter into a shared services agreement with Raycom Media beginning in February 2012. This outsourcing arrangement resulted in CBS affiliate KOLD-TV taking over daily operations of KMSB and KTTU and moving their advertising sales department into the KOLD studios (however, they remained employees of Belo). All remaining positions at the two stations were eliminated and master control moved from KTVK in Phoenix to KOLD.[4] The transfer of KMSB's operations occurred in several stages, with newscasts moving to KOLD's studios on February 1 and other operations being taken over by KOLD in the following weeks.[5][6]

On June 13, 2013, the Gannett Company announced that it would acquire Belo. However, as Gannett holds a partial ownership stake in the publisher of the Arizona Daily Star, the KMSB license was instead sold to Sander Media, LLC, operated by a former Belo executive, Jack Sander. While the other Belo stations acquired by Sander in the deal have various shared services agreements with Gannett, Raycom Media continues to operate the two stations, and the Belo employees handling advertising sales became Gannett employees.[6][7] The sale was completed on December 23.[8] On June 29, 2015, Gannett's publishing operations were spun off, with the remainder renamed Tegna, Inc.[9] Shortly afterward, Sander Media filed with the FCC to transfer KMSB's license to Tegna.[10]

News operations

KMSB produces an hour-long 9 o'clock newscast each night. After not having a newscast for nearly 20 years, KMSB began a 9 p.m. newscast in 2003.[13] From the newscast's inception until August 2008, it was produced by sister station KTVK in Phoenix using KTVK news anchors and meteorologists, with live reports from KMSB reporters and NBC affiliate KVOA. Sports began originating entirely from the KMSB studios in Tucson in 2006.

In August 2008, the news portion of 9 p.m. newscast began originating out of the KMSB studios as well with Lou Raguse as anchor. In January 2009, the newscast expanded from 30 minutes to one hour nightly and began locally produced weathercasts, thus completing the transition of the newscast from Phoenix to Tucson. The station was one of the last top-100 market Fox affiliates to air late-evening news.

In March 2010, it was announced that KMSB's news partnership of seven years with KVOA would be ending.[14] KMSB's news staff, operating out of KVOA's building since 2003, would relocate to KMSB's studios. This move would unite the news staff with the sports department and weather announcers, both of whom have been working out of KMSB's building.

On February 1, 2012, KOLD-TV took over the operations of KMSB—taking over production responsibilities of KMSB's nightly prime time newscast at 9, as well as launching a two-hour weekday morning show (from 7 until 9), Fox 11 Daybreak, on the station. In addition, KTVK's Good Morning Arizona will no longer be seen on KMSB (the 5–7 a.m. portion will be replaced by syndicated programming), and Fox 11 Sports Force will be canceled (with the Sunday 9 p.m. newscast now airing for an hour).[15][16][5] The same day, KMSB's website was folded into that of KOLD, and re-branded Tucson News Now.[17] As a result, the newscasts on KMSB are now in high definition (prior to the beginning of the SSA, KMSB was the only Belo station that continued to air its late night newscast in pillarboxed 4:3 standard definition because its then in-house news production lacked widescreen- or high-definition-capable cameras).
