'''KMSB''' (channel 11) is a [[television station]] in [[Tucson, Arizona]], United States, affiliated with the [[Fox Broadcasting Company|Fox]] network. It is owned by [[Tegna Inc.]] alongside dual [[The CW|CW]]/[[MyNetworkTV]] affiliate [[KTTU-TV]] (channel 18); Tegna maintains a [[shared services]] agreement (SSA) with [[Gray Media]], owner of [[CBS]] affiliate [[KOLD-TV]] (channel 13), for the provision of studio space and technical services and the production of local newscasts for KMSB.<ref name="ssa20">{{cite web|url=https://publicfiles.fcc.gov/api/manager/download/96acf167-0e5c-c4c3-e9d2-1f1fef643e50/ef0b4b66-8ed8-4ef8-9b47-4e290627fcec.pdf|title=Shared Services Agreement|publisher=Federal Communications Commission|date=January 3, 2020|access-date=July 4, 2022|archive-date=July 4, 2022|archive-url=https://web.archive.org/web/20220704053847/https://files.fcc.gov/download/ef0b4b66-8ed8-4ef8-9b47-4e290627fcec.pdf|url-status=live}}</ref> The three stations share studios on North Business Park Drive on the northwest side of Tucson (near the Casas Adobes neighborhood). KMSB's lone transmitter is located atop [[Mount Bigelow (Arizona)|Mount Bigelow]]; as a result of the transmitter's location, residents in the northern part of Tucson, [[Oro Valley]], and [[Marana, Arizona|Marana]] do not receive adequate reception of the station.

The station went on the air in 1967 as KZAZ, an [[independent station]] licensed to serve [[Nogales, Arizona]], with a coverage area including Nogales and Tucson. Under the ownership of Roadrunner Television from 1976 to 1984, it developed into a homespun station with increased popularity and programming. Roadrunner sold the station to a company controlled by [[The Providence Journal]] Company in 1985; it affiliated with Fox in 1986. After producing local news programming in its first 14 years on air, local news was revived under [[Belo Corporation]] ownership in the 2000s. The station's separate local news department was dissolved when Belo entered into the SSA with KOLD-TV in 2011, with KOLD-TV producing several dedicated newscasts.

It would be another 18 years before local news returned. On June 16, 2003, the hour-long ''Fox 11 News at Nine'' began to air as part of a three-way partnership.

In 2010, KMSB began to plan for the introduction of a four-hour morning newscast that fall, to be called ''Daybreak''.
