MRC analysts reviewed all 47 gun policy stories (41 full segments, 6 anchor read briefs), plus 10 other stories that mentioned gun policy on the Big Three networks’ evening (ABC’s World News Tonight, CBS Evening News, NBC Nightly News) and morning show programs (ABC’s Good Morning America, CBS This Morning, NBC’s Today), beginning with the evening (June 12) after the shooting through Friday evening, June 17.

The study found a huge disparity in the airtime devoted to advancing more gun control versus arguments in favor of gun rights.

Time spent arguing in favor of more gun control overwhelmed time devoted to opposing gun rights by 65 minutes and 12 seconds, to just eight minutes and 12 seconds.

CBS was the most stridently anti-gun rights network. By a whopping 10 to 1 ratio, CBS devoted more time to arguing in favor of gun control (30 minutes, 40 seconds) to time that supported gun rights (2 minutes, 56 seconds).
