This decision comes after Comcast has been running ads for some gun and hunting groups for decades. Comcast chose this new position after purchasing NBCUniversal, which has a long-standing ban against firearm, ammunition and firework advertisements.
This move brings Comcast in line with its competitors, Time Warner Cable and Cox Communications.
Cox already had a ban similar to the one Comcast has now instituted and Time Warner Cable announced in January that it was banning "ads showing semi-automatic weapons and guns pointed at people."
Gun control advocates praise Comcast's "brave move," while gun store owners say their profession has been unjustly singled out by Comcast.
