KCSO was founded bycountry-western performerChester Smith and his companySainte Partners II, L.P. and first signed on the air in 1999. It was the last station to be owned by his company. On August 8, 2008, Chester Smith died of heart failure atStanford University Medical Center inPalo Alto, California.[4] The station continued operating under the Sainte banner until it was sold to Serestar Communications Group in 2013. Sainte folded shortly thereafter.
In 2014, Serestar Communications agreed to purchase both KMUM-CD and KMMW-LD fromViacom for a disclosed amount. The sale of both stations was finalized on September 25, 2014. Prior to the sale, both of the stations dropped theTr3́s affiliation and switched to Telemundo. After the sale, they became sister stations and translators to KCSO-LD. Also in 2014, KCSO began simulcasting in widescreen standard definition on KSPX-TV's seventh subchannel (displayed as channel 33.2) to reach the entire market due to KCSO's low-power status. The simulcast was discontinued in October 2021.
Serestar agreed to sell KCSO-LD, KMUM-CD, and KMMW-LD toNBCUniversal on November 28, 2018, as part of a $21 million deal.[5] The sale was completed on March 5, 2019.[6] As a result, KCSO-LD became the sixth television station in the Sacramento market (excluding translator stations) to be owned-and-operated by its affiliated network.
In April 2022,CW owned-and-operated stationKMAX-TV (channel 31, now anindependent station) resumed the widescreen SD simulcast from KSPX-TV on a new subchannel also displayed as channel 33.2.
In March 2025, the simulcast returned to KSPX-TV inhigh definition on subchannel 33.2. An SD simulcast remains on KMAX-TV, but is now displayed as channel 31.7.
KCSO launched a local news department (with newscasts branded asNoticiero 33) following its sign-on. The half-hour local evening news program was broadcast every Monday through Friday at 6 p.m. However, it had lowratings and was canceled after five years.
Later, news briefs were aired online (branded asTelemundo 33 Al Día). In late 2014, it started airing morning news briefs calledNoticias 33 por la mañana, which aired at 25 and 55 minutes past the hour from 7 to 9 a.m. during Telemundo'sUn Nuevo Diamorning news program.
On November 6, 2016, KCSO re-launched a weekday half-hour long newscast at 6 p.m. (initially branding asNoticiero Telemundo 33, later asNoticias Telemundo Sacramento, now asNoticias Telemundo California after the purchase by NBCUniversal), 11 years after its initial newscast was canceled. It directly competes withUnivision owned-and-operatedKUVS's long-established (and for several years, the Sacramento area's only) Spanish-language newscast.
In 2017, a weeknight 11 p.m. newscast (branded asNoticias Telemundo California) was launched, further competing with KUVS.Noticias Telemundo California is simulcast onFresno sister stationKNSO.
On March 18, 2020, one year after the purchase by NBCUniversal, the station launched 5 and 5:30 p.m. newscasts, and began simulcasting all of their newscasts on KNSO.
