WHO-DT (channel 13) is a television station in Des Moines, Iowa, United States, affiliated with NBC and owned by Nexstar Media Group.

Although WHO-DT's call letters sound like "who" if pronounced as a word, the station is never referred to in that manner; it is always mentioned on air as "W-H-O".

It was signed on by the Tri-City Broadcasting Company,[3] which was owned by the Palmer family, owners of WHO radio (AM 1040 and FM 100.3, now KDRB).

[6] On January 4, 2007, The New York Times entered into an agreement to sell its entire television division, including WHO-TV, to private equity group Oak Hill Capital Partners.

Oak Hill created Local TV LLC as a holding company for the former New York Times stations.

For instance, it only ran Days of Our Lives for 37 of its 57 years on NBC, beginning with the soap opera's 20th season and ending with its move to the streaming service Peacock in September 2022; in the 1960s and 1970s, the station aired a 90-minute movie between 12:30 and 2 p.m. For its first 23 years on the air, WHO-TV had a competing station in KQTV/KVFD-TV in Fort Dodge.

[28] Following Cafferty's departure, his place was taken by Greg Burden, a former college basketball player from Los Angeles who was hired away from KMOX-TV (now KMOV) in St. Louis.

Although his personality clicked with fellow newscasters, Thomas complained that the fact that Burden was bigger than him had made him look like a circus midget.

[29] Later in the decade the humor on Eyewitness News, combined with the two anchors' constant ribbing, was a source of annoyance for the Palmers, particularly when audience research showed that viewers compared Phil Thomas to the then-budding comedian Steve Martin and bloopers from the news were on the inaugural show of NBC's Real People.

On September 2, 2008, WHO-TV entered into a news share agreement with Fox affiliate KDSM-TV (owned by the Sinclair Broadcast Group).

The big three station then began producing a Des Moines-based prime time newscast known as Channel 13 News at Nine on Fox 17.

Originating from WHO-TV's primary set at its facilities on Grand Avenue in Downtown Des Moines (with separate duratrans indicating the Fox show), the nightly prime time program currently airs for an hour on weeknights and thirty minutes on weekends.

Unlike other outsourced news arrangements at Sinclair-owned television stations, KDSM uses the same music and graphics package scheme as seen on this NBC affiliate.

[33] On May 19, 2010, WHO-HD became the first commercial station in Des Moines to launch fully into high definition television.
