WSDZ is an AMradio station in Belleville, Illinois, located at 1260 kHz. It is under ownership of The Walt Disney Company and features programming from Radio Disney. The station began in 1947 as WIBV ("Belleville's Voice"). WIBV aired various types of music, and broadcasting a variety of high school sports into the Metro-East area for many years, until the mid-1990s, when it became an all-news/talk station, a fore-runner of KTRS. WIBV became WSDZ, when it transferred all of its programming over to KSD-AM, which became KTRS in early-1997. Since then, it has been the Radio Disney affiliate for the Greater St. Louis Metropolitan area.
