CBS News and CBS Television Stations will release CBSN Chicago in 2020 though. I remember this after New York, Los Angeles, San Francisco, Boston had their local editions of CBSN released.
Sacramento, Chicago, Philadelphia, Pittsburgh, Miami, Denver, Minneapolis and Dallas will release their local edition of CBSN sometime in 2020.
I live in the Providence area and can receive WBZ 4 but CBS News Boston isn't available.
