 KTVX traces its history back to the November 1946 sign-on of W6XIS, the first television station in Utah, which operated under an experimental broadcast license.The station began regular broadcasts on April 19, 1948 as KDYL-TV; it was originally owned by the Mountain Broadcasting Corporation (operated by Sid Fox), along with KDYL radio (1320 AM, now KNIT, and 98.7 FM, now KBEE).The floor in the original studio facility was sloped and cameras would easily roll.
