Radio 93XRT (WXRT)

WXRT-FM, also known as WXRT 93.1, XRT, and 93-XRT is a AAA radio station in Chicago, Illinois. For many years their slogan has been "Chicago's Finest Rock". WXRT-FM is a primary sponsor of the Chicago nonprofit Rock For Kids.The format as it exists today began in 1972 as a night-time-only freeform rock experiment, sharing the 93.1 frequency with a variety of different ethnic and foreign language programming that aired during the daylight hours. The part-time progressive rock format was gradually expanded until by 1976 it aired 24 hours a day. By the 1980s the station played primarily New Wave and alternative music of that time. As the 1990s approached the station opted to stay with its core audience and move to a AAA format. The office of the radio station was located on west Belmont Ave. on the northwest side of Chicago, until September 6, 2008, when it was relocated to the NBC Tower in downtown Chicago. On March 16, 2010, it was again relocated to the Prudential Plaza.WXRT was locally owned until 1995. It was then purchased by Westinghouse, which had acquired WMAQ 670 (which has since changed call letters to WSCR) a few years before. WXRT became part of the CBS conglomerate in 1996 when Westinghouse and CBS merged. CBS later merged with Infinity Radio, keeping the Infinity name for its radio division. CBS and Viacom would merge in 2000, making WXRT an Infinity Radio station whose parent companies were CBS and Viacom. In December 2005, Infinity Radio officially became CBS Radio in anticipation of the CBS/Viacom split up.
