KIDK is the CBS-affiliated television station for Southeastern Idaho, Southwestern Montana and Northwestern Wyoming that is licensed to Idaho Falls. It broadcasts a high-definition digital signal on UHF channel 36 (or virtual channel 3.1 via PSIP) from a transmitter on East Butte in northern unincorporated Bingham County along the Idaho National Laboratory border. The station can also be seen on Cable One channel 3 and in high definition on digital channel 1003.
Owned by VistaWest Media, LLC, KIDK is sister to low-powered primary Fox and secondary MyNetworkTV outlet KXPI-LD and both are operated through a shared services agreement with the News-Press & Gazette Company. This arrangement makes the two stations sister to ABC affiliate KIFI-TV and all three share studios on North Yellowstone Highway/U.S. 26 in Idaho Falls. Syndicated programming on this station includes Two and a Half Men, The Big Bang Theory, The Doctors, and Dr. Phil among others.
The station was founded on December 20, 1953 as KID-TV, co-owned with KID radio (AM 590 and FM 96.1). The station has been a primary affiliate of CBS since its debut, however it carried secondary affiliations with the DuMont Television Network until its 1955 shutdown, NBC until 1961 (moving to KIFI-TV thereafter until swapping affiliations with KPVI in 1996) and ABC until 1974 (when KPVI became a primary affiliate of the network upon that station's debut). KID-TV changed its callsign to KIDK on December 18, 1984, when the radio stations were sold. After dropping its secondary NBC affiliation, KIDK had an exclusive affiliation with CBS until January 1995, when it began carrying UPN as a secondary affiliation (KPID-LP, now KXPI-LD, affiliated with the network when it debuted in June 2001; however, KIDK continued its secondary affiliation with the network until 2003).
On December 9, 2010, Fisher Communications announced that it had entered into a shared services arrangement with News-Press & Gazette Company-owned ABC affiliate KIFI-TV, under which KIDK would be run out of the KIFI facility and 27 KIDK staffers would be laid off. The move placed KIDK under the co-management of the station that accepted the ABC and NBC affiliations that KIDK formerly carried in the same secondary capacity prior to becoming an exclusive CBS affiliate. The transaction was completed on January 1, 2011.
On April 11, 2013, Fisher announced that it would sell its stations to the Sinclair Broadcast Group. The deal was completed on August 8, 2013. Shortly beforehand, a deal was reached to sell KIDK and KXPI to VistaWest Media, LLC, a company based in St. Joseph, Missouri (where NPG is also based); the stations will remain operated by NPG under a shared services agreement. The sale was finalized on November 29. 
The station's digital signal is multiplexed:
|Channel||Video||Aspect||PSIP Short Name||Programming|
|3.1||1080i||16:9||KIDK-DT||Main KIDK programming / CBS|
|3.2||720p||FoxKXPI||Simulcast of KXPI-LD|
KIDK shut down its analog signal, over VHF channel 3, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 36. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 3.
As a result of the SSA between KIDK and KIFI, the former consolidated its news department into KIFI's studios. The ABC outlet then began producing all of KIDK newscasts. The CBS affiliate modified its local news schedule in order to reduce opportunities for direct competition with KIFI. More specifically, KIDK dropped its weekday morning show in favor of CBS Morning News repeats making that station one of a few in the United States that does not provide a local news broadcast in the time slot.
Its separate newscasts airing weeknights at 5 and 6 on KIDK were dropped in favor of one seen at 5:30 while KIFI airs ABC World News. KIDK provides the CBS Evening News at 5 preceding its local show. This station still offers a separate broadcast weeknights at 10 that does compete with KIFI. All local news programming produced for KIDK originates from KIFI's primary set except with modified studio elements, such as duratrans and on-screen graphics, indicating the specific channel airing news.
In order to maintain individual on-air identities and branding, KIDK and KIFI have separate graphic schemes and news music packages. The two maintain primary weeknight personalities (such as news anchors) that only appear on one channel. On weekends, KIFI offers its own early evening newscast at 5 while KIDK follows at 5:30. The two television outlets simulcast together at 10 although the broadcast can be delayed or preempted on one channel due to network obligations. The CBS affiliate continues airing a nightly prime time newscast at 9 on sister station KXPI (now produced by KIFI). Prior to the SSA formulation, that outlet also rebroadcast KIDK's weekday morning show at 7.
