KGMB (channel 5) is a television station in Honolulu, Hawaii, United States, serving the Hawaiian Islands as an affiliate of CBS.

The stations share studios on Waiakamilo Road in Honolulu's Kapālama neighborhood; KGMB's transmitter is located in Akupu, Hawaii.

[3] KGMB-TV was originally owned by J. Howard Worrall along with KGMB radio (AM 590, now KSSK) and operated from studios on Kapiolani Boulevard in Honolulu.

In 1973, a partnership led by future Hawaii congressman Cecil Heftel bought KGMB-AM-TV, then turned around and sold the KGMB stations to Lee Enterprises in 1977.

Emmis already owned KHON-TV, so it had to obtain a cross-ownership waiver for the purchase of KGMB from the Federal Communications Commission, to bypass the recently passed duopoly rules that forbid common ownership of two of the four highest-rated stations in a single market.

KIKU, an independent station specializing in Japanese programming, became a secondary UPN affiliate on November 1, 2004, and remained with the network until its closure on September 15, 2006.

Emmis then announced on February 20, 2007, that KGMB and its satellites had been sold to MCG Capital Corporation for $40 million,[4] resulting in one of the rare instances involving a complete separation of a television station duopoly.

Shortly after MCG Capital Corporation took over, KGMB adopted a logo similar to the one it used in the early 1980s and also rolled out a new graphics package for its newscast and a new website.

[5] The resulting ownership arrangement of the stations generated some controversy, as it had the effect of Raycom trading KFVE to MCG Capital in return for KGMB.

Raycom Media president Paul McTear staunchly defended the SSA, stating it would "preserve three stations that provide important and valuable local, national and international programming to viewers in Hawaii.

[12] Beginning in 2016, the Hawaii News Now (HNN) group of KGMB, KHNL, and KFVE severed ties to the Nielsen ratings.

Under the deal, which is expected to receive regulatory approval in the first quarter of 2019, Nexstar also intends to integrate KFVE's operations into KHON's studio facilities at the Hawaiki Tower on Piikoi and Waimanu Streets.

As such, Nexstar will likely assign new call letters to the channel 9 license as well as acquire programming to replace that being maintained by Raycom post-acquisition (which may include shifting the programming on KHON's CW-affiliated DT2 feed to the KFVE license, and/or the retention of the MyNetworkTV affiliation, which Raycom did not include in the KFVE intellectual property transaction.

[25] KGMB clears all CBS programming, although it will occasionally preempt prime time shows until the overnight hours in order to broadcast locally produced specials.

On weekends during the Hawaii Warriors football season, KGMB airs The Nick Rolovich Show, which recaps the last game played and previews the next one.

KGMB currently broadcasts most of its programming, including CBS network shows and sports events such as NFL and college basketball games, in full 1080i high definition.

A temporary agreement was reached between KGMB and Oceanic Time Warner to carry Super Bowl XLI in high definition.

The program was dropped on August 17, 2007, to make room for a new morning newscast titled Sunrise on KGMB 9, which launched on September 17.

However, on December 13 of that year, KGMB announced that those plans had been put on hold due to the possibility of relocating its studio facilities.

With the launch of the Hawaii News Now operation on October 26, 2009, KGMB began broadcasting its local newscasts in high definition.
