In January 2017, WLS and WLS-FM moved from its 190 N. State Street studios to its new studios in NBC Tower on North Columbus Drive in Streeterville. In addition, the station became the new affiliate of NBC News Radio. On January 2, 2017, the station added the on-air team of Bob Sirott and Marianne Murciano from WGN (AM); the former marking his return to WLS for the first time since 1980. However, Sirott and Murciano were cut from the station's lineup, beginning January 1, 2018.
