WHO-DT (channel 13) is a television station in Des Moines, Iowa, United States, affiliated with NBC and owned by Nexstar Media Group. The station's studios are located on Grand Avenue in downtown Des Moines, and its transmitter is located in Alleman, Iowa. 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." History WHO-TV signed on the air on April 15, 1954, as the third television station in Des Moines, after WOI-TV (channel 5) and KGTV (channel 17). It was signed on by the Tri-City Broadcasting Company, which was owned by the Palmer family, owners of WHO radio (AM 1040 and FM 100.3, now KDRB). The Palmers had competed with KIOA for the channel 13 license and won it after reaching a settlement. It has always been an NBC affiliate, having inherited this affiliation from WOI-TV and owing to WHO's long affiliation with the NBC Radio Network. The Palmers sold off their broadcast holdings in 1996, with WHO-TV and sister station KFOR-TV in Oklahoma City going to The New York Times Company. Earlier that year, a joint plan by the Sinclair Broadcast Group (at the time in the process of purchasing Oklahoma City's then-UPN affiliate KOCB) and River City Broadcasting (then owner of Fox affiliate KDSM-TV) to purchase Palmer Communications, which since the 1970s had been the name of the Palmer family's holding company, fell through; Sinclair would have purchased WHO outright while River City would have received KFOR. However, River City was in the process of being merged into Sinclair, which would have resulted in duopolies, which were at the time prohibited by Federal Communications Commission ownership rules, in both the Des Moines and Oklahoma City markets. Up to that time, channel 13 had been the last locally owned commercial station in Des Moines. WHO radio, which was eventually acquired by Jacor Communications (which later merged with Clear Channel Communications), continued to occupy the same building until it moved to another building in 2005. While WHO-TV was co-owned with WHO radio, it used an owl as its mascot. 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
