KTIV is an NBC television station in Sioux City, Iowa, broadcasting on digital channel 41. KTIV also carries The CW Television Network, which replaced The WB network in September 2006, on its 4.2 digital subchannel, and on June 6, 2013, MeTV launched its new digital subchannel on 4.3, and it identifies locally as MeTV Siouxland.
After overcoming some construction obstacles, including having to raise the microwave tower height twice to avoid interference with a tree which blocked the microwave signal, KTIV made its broadcasting debut on Sunday, October 10, 1954. That first broadcast evening included four NBC shows: "People are Funny" at 6 p.m.; "The Liebman Spectacular" from 6:30-8 p.m.; "The Television Playhouse" from 8-9 p.m.; and "The Loretta Young Show" from 9-9:30 p.m.
The station has always been an NBC affiliate, but it shared ABC programming with KVTV/KCAU-TV until September 2, 1967, when KCAU switched its primary affiliation to ABC. During the late 1950s, the station was also briefly affiliated with the NTA Film Network.
In June 2011, KTIV's newscasts began to be broadcast in high definition. It was the second station in the Sioux City market (after KCAU) to begin broadcasting news in HD, and the last station in the market to begin using a widescreen format for local news.
The station's digital signal is multiplexed:
|Channel||Video||Aspect||PSIP Short Name||Programming|
|4.1||1080i||16:9||KTIV-DT||Main KTIV programming / NBC|
KTIV shut down its analog signal, over VHF channel 4, at 1:30 p.m. on February 17, 2009, as part of the federally mandated transition from analog to digital television (which Congress had moved the previous month to June 12). The station's digital signal remained on its pre-transition UHF channel 41, using PSIP to display KTIV's virtual channel as 4 on digital television receivers.
