CBS News (United Republics TV channel)

2000-2008
Following the closure of then-sister channel All News Channel in 2002, select staff and resources moved to CBSN, although Viacom labeled this move as more of a merger, especially since CBSN had wider coverage than ANC plus the fact most of co-owner Hubbard Broadcasting's stations were affiliated to competing networks EBC and NBC, who already owned their own cable news channels.

2014-2021
In 2018, CBSN became a hybrid service, consisting of a nationwide channel and a network of regional channels named CBSN Local, carried terrestrially as a subchannel on CBS O&Os in their respective region as well as on cable and satellite television providers and for free on CBS News website and mobile app.
