KRIS-TV began broadcasting on May 22, 1956 as the first VHF television station in the area beating former rival KZTV by four months. It aired an analog signal on VHF channel 6 and had studios on South Staples Street in Downtown Corpus Christi. The channel has always been an NBC affiliate but shared secondary ABC status with KZTV until KIII launched on May 4, 1964. In 1989 it was a secondary Fox affiliate carrying a few shows during syndicated hours on the weekends. This ended in 1991 due to other affiliates becoming available on cable via Foxnet. KRIS-TV was the first television station in the United States to air hard liquor ads after a self-imposed 1948 industry ban was lifted. A commercial for Crown Royal whiskey aired on the station in 1996 featuring a puppy with a diploma and another carrying a Crown Royal bag in its mouth. Cordillera Communications bought the station in 1998.
