KILT (610 AM, "Sports Radio 610") is a Sports/Talk formatted radio station in the Houston, Texas, metropolitan area. The station is currently owned by CBS Radio. KILT shares its call letters with its sister station 100.3 FM, which airs a country music format. KILT was the legendary Top 40 outlet in Houston as the "Big 610" until 1981 when it dropped the longtime format and moniker to simulcast KILT-FM "FM 100", which had recently flipped formats from Album Rock to Country itself. After 13 years of running country music on 610, it moved to sports talk in 1994. KILT is the flagship station of the NFL's Houston Texans and the Texans Radio Network.
