An announcer then said the official last words: "The final broadcast, the end of Radio 670, WMAQ, Chicago." After the NBC chimes were played one more time and a WMAQ jingle, the era for the station that was "First In Chicago" came to an end. Following the sign-off, WMAQ ran a loop of "Score" promos for six hours before starting a full simulcast of WSCR for a two-week transitional period. 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, the 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.

Viacom, which had acquired the shares in Infinity Broadcasting it did not already own on February 21, 2001, split into two companies at the end of 2005; Infinity became part of CBS Corporation, and in preparation was renamed CBS Radio on December 14, 2005. In 2010, WSCR's studios were moved to Two Prudential Plaza, home to several other CBS Radio stations. The Chicago Cubs made WSCR the flagship of their radio network following the White Sox' departure to WLS. When the Cubs left WGN for CBS Radio following the 2014 season, the Cubs were heard on WBBM 780 AM.
