KNOE's studios are located on Oliver Road north of Louisville Avenue in Monroe, while its transmitter is located south of Monroe in Columbia, Louisiana. The station also operates a low-powered translator, K18AB-D in El Dorado, Arkansas, which rebroadcasts KNOE's digital signal in high definition. Even though the translator is broadcast on channel 18, it remaps to channel 8 via PSIP.
KNOE-TV went on the air on September 27, 1953. Initially, the station had a 774-foot tower, weighing 4 tons and costing $65,000. At the time, it was the most powerful tower in the American South. KNOE is the oldest surviving station in the northern part of Louisiana. Its sign-on forced its only competitor, KFAZ (channel 43), off the air in the summer of 1954. James A. Noe, Sr., former governor of Louisiana, owned the television station as well as KNOE radio (AM 540, now KMLB, and FM 101.9, now KMVX).
The station affiliated with all four television networks of the "golden age": CBS, NBC, ABC and DuMont. During the late 1950s, the station was also briefly affiliated with the NTA Film Network. KNOE continued to air ABC programming until 1972 when KTVE became a primary ABC affiliate and NBC programming until 1974 when KLAA signed-on.
Noe died in 1976, and passed the station to his son, James "Jimmie" Noe, Jr. The Noes continued to own the station until 2007, when it was sold to Dallas-based Hoak Media. The sale closed on October 3 of that year. The family had already sold KNOE AM to Holladay Broadcasting in November 2006, and would sell KNOE-FM to them the following year. The sale of the stations followed Jimmie Noe's death from cancer in 2005, in which it was decided by the family to leave the broadcasting business. On August 25, 2010, KNOE started broadcasting syndicated programing in high definition.
On November 20, 2013, Gray Television announced it would purchase Hoak Media in a $335 million deal. The deal also included the acquisition of Parker Broadcasting, owner of ABC affiliate KAQY, which KNOE had operated under a local marketing agreement since 2008. However, due to recent scrutiny by the FCC regarding LMAs (KAQY was originally to be sold to the shell company Excalibur Broadcasting, and would have maintained its LMA with Gray), KAQY was sold to a minority-owned company, and KNOE would forgo any operational agreements with the new owner. In September 2014, KAQY signed off, and it programming was moved to KNOE's second digital subchannel, displacing The CW to the third.
The station's digital signal is multiplexed:
|Channel||Video||Aspect||PSIP Short Name||Programming|
|8.1||1080i||16:9||KNOE-HD||Main KNOE-TV programming / CBS|
|8.3||480i||KNOE-CW||Monroe/El Dorado CW|
KNOE-TV shut down its analog signal, over VHF channel 8, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal relocated from its pre-transition VHF channel 7 to channel 8.
KNOE-TV has been the dominant news station in the Ark-La-Miss for more than a quarter-century. It has won numerous state, regional and national journalism awards, including the 2008 Alfred I. duPont-Columbia University Award for News Director Taylor Henry's investigative series on rogue members of the Louisiana National Guard who looted stores they were deployed to protect during Katrina.
During the weekdays, KNOE airs a 2-hour morning newscast called Good Morning Ark-la-Miss (the last 30 minutes is simulcast on KNOE-DT2 (ABC KAQY), as well as half hour newscasts at Noon, 5 PM, 6 PM, and 10 PM. During the weekends, the station airs 2 half hour newscasts at 6 PM on Saturdays and 5:30 PM on Sundays and 10 PM both days. Newscasts are typically branded as KNOE 8 News and have been since 2008.
On November 1, 2010, KNOE debuted a new news set, fit for high definition broadcast. On January 17, 2011 KNOE began broadcasting its local newscasts in high definition, becoming the first station in the Ark-La-Miss region to do so; in-studio as well as in the field.
This episode, framed around KNOE's "Good Morning ArkLaMiss" morning show, featured a slightly modified "KNOE News" logo (minus the CBS logo) but retaining the slogan "Your Breaking News And Weather Authority" throughout.
