ownership interests in FSN Bay Area and FSN New England to Comcast for $570 million (the San Francisco Giants were added as a partner in FSN Bay Area, when the team acquired a 30% stake in the network on December 10); subsequently, FSN New England rebranded as Comcast SportsNet New England in July 2007, while FSN Bay Area was rebranded as Comcast SportsNet Bay Area on March 31 of that year. Integration with NBC Sports As the result of the acquisition of NBC Universal by Comcast in February 2011, the operations of CSN, along with sister national sports networks Versus and Golf Channel, were integrated into the NBC Sports division. CSN adopted the new NBC Sports branding that was launched in January 2012 alongside the relaunch of Versus as NBC Sports Network, but plans to fully rebrand the networks under the NBC Sports were shelved.

After filing an involuntary Chapter 11 bankruptcy petition for the network on September 27, 2013, to "resolve structural issues affecting CSN Houston's partnership," DirecTV Sports Networks and AT&T acquired Comcast SportsNet Houston on August 6, 2014 as part of a reorganization plan (with DirecTV as majority owner at 60%). The network was then integrated into DirecTV-operated Root Sports group, which relaunched it as Root Sports Southwest on November 14, 2014. In markets that didn't have an affiliate of that group, Comcast SportsNet also carried national programming distributed by competing regional sports network chain FSN (which included various college sports and UEFA Champions League soccer), a relationship that traced back to the launch of Comcast SportsNet Philadelphia (which took over the FSN programming rights
