On June 23, 2015, WLS announced that they had picked up broadcasting rights for Chicago White Sox baseball starting with the 2016 season. In addition, WLS had also picked up broadcasting rights for the Chicago Bulls, beginning with the 2016-17 NBA season. Due to Cumulus's January 2018 Chapter 11 bankruptcy, the carriage rights were terminated in the filing; the Bulls moved to WSCR with immediate effect at the start of February, with the White Sox shifting to WGN several weeks later.
