As part of this exchange, Infinity changed the WMAQ call sign to WSCR on August 15, 2000; changed the station's format to sports radio; and re-branded the station as "670 The Score". All on- and off-air personnel were concurrently transferred to the new WSCR. In effect, this new WSCR (670 AM) licensed to Chicago became the successor to the previous WSCR (1160 AM) licensed to Chicago—which concurrently changed their call sign to WXRT (AM), then was sold that November to Salem Communications, and now operates as WYLL. The "Score" format, branding and call letters had its origins on the former WSCR (820 AM), which launched on January 2, 1992; the second WSCR on the 1160 AM facility debuted on April 17, 1997. All three iterations of WSCR utilized the same studios at 4949 West Belmont Avenue in Chicago's Cragin neighborhood—shared with WXRT—from 1992 until moving to the NBC Tower in 2001, using the facilities that WMAQ had vacated a year earlier.
