After NBC Sports Chicago ended broadcasting operations, most of its channel positions, social media presences and existing followers, transferred to CHSN.

In November 2003, Jerry Reinsdorf, Bill Wirtz, and the Tribune Company decided to end their cable television agreements for the Bulls, White Sox, Cubs, and Blackhawks with FSN Chicago, stripping that network of broadcast rights to all of the professional sports teams in the Chicago area.

After Rainbow Media shut down FSN Chicago on June 23, 2006,[5] Comcast SportsNet Chicago acquired the regional cable television rights to broadcast sports events, discussion and entertainment programs intended for national distribution to the Fox Sports regional networks.

The team renewed CSN Chicago's broadcast rights (with the network carrying the bulk of the games), while local broadcasts were split between CSN Chicago and WGN-TV effective with the 2008–09 season; all of the team's games (both home and away) would be televised in high definition (due to the NHL's broadcast contracts, WGN-TV was barred from carrying its share of Blackhawks telecasts on its former national superstation feed WGN America, although its game telecasts were available in Canada through the station's carriage as a superstation on domestic cable and satellite providers).

The updated graphics were implemented on CSN's live game coverage and all studio shows, with the exception of SportsNet Central.

[12] SportsNet Central would ultimately implement a new on-air look of its own and on April 14, 2014, in conjunction with that change, the program switched to the updated graphics package introduced three years earlier.

[13] On January 2, 2019, the White Sox, Bulls, and Blackhawks agreed to an exclusive five-year deal with NBC Sports Chicago beginning in the fall of 2019, ending their broadcasts on WGN-TV.

[14][15][16][17][18] In April 2019, the network acquired regional rights to the Chicago Red Stars of the National Women's Soccer League.

The network went dark following a commercial for The Nature Conservancy before putting up a placeholder for minutes saying that the channel "is no longer in service".

[25] The channel had held the broadcast rights to games of the now-defunct Chicago Rush of the Arena Football League.

[27] The network also carried collegiate sports events including Loyola Chicago men’s and women’s basketball and a package of Missouri Valley Conference basketball games, including the first round and quarterfinals of Arch Madness, syndicated by Bally Sports Midwest.

Before digital cable services were expanded, the Plus channels aired part-time, temporarily replacing networks such as CLTV or C-SPAN2 when necessary.
