KMEG 14 was started in Sioux City more than forty years ago by a group of local investors led by Bob and Norma Donovan.  The Donovan's are credited as the founders of the station whose vision, early struggles and sacrifices have made KMEG's long term success possible.  The call letters MEG (preceded by the letter ‘K' as is mandated by FCC law) were selected in honor of Bob and Norma's daughter MEG who died in 1998.

Bob Donovan was a founding board member of the Arbitron Advisory Board and a long standing member of the CBS Affiliates Board as well as a leader for numerous Sioux City community organizations.  Bob passed in 1997.

KMEG 14 has served the Sioux City DMA since 1968.  Following the local owner group with the Donovan's in charge, KMEG sold to Maine Radio.  In 1998, Waitt Media purchased the station from Maine Radio. Under Waitt's ownership, KMEG14 received significant upgrades, including the addition of evening and late-night newscasts, and an increase of tower height to 2,000 feet and power to five million Watts, which transformed the station's signal from Sioux City metro-only to full-market coverage spanning 23 counties in Northwest Iowa, Northeast Nebraska and Southeastern South Dakota.

In May 2005, Pappas Telecasting (the licensee for KPTH, the Sioux City FOX affiliate) began operating KMEG under a Shared Services Agreement, with Waitt Media retaining the FCC license. In January 2009 the management of the station came under the direction of New World Television in the form of a LMA (Local Marketing Agreement).  Ownership remains Waitt Media.  Affiliated with the CBS Network, KMEG is dedicated to quality programming, bringing local news, sports, weather, and community affairs to viewers. 

KMEG News is known for its focus on the local communities that make up the Sioux City market.  Newscasts are branded as "Your Hometown News", and the station works every day to live up to its brand.  Copyrighted franchises of the station include ‘Proud to be a Hometown Farmer', ‘Hometown Zip Code' and ‘For Goodness Sakes'.  GAME NIGHT is the local sports feature.  KMEG News is the only local newscast to receive multiple Emmy nominations.

The station is home to top-rated CBS Network programming such as CSI, Survivor, Navy NCIS, Without a Trace, 2½ Men, and CBS Sports including NFL and NCAA football, the Masters Tournament and PGA Championship, and the NCAA Basketball Final Four.
