(Adds Hertz announcement it has ended NRA discount program)
NEW YORK, Feb 23 (Reuters) - More than half a dozen U.S. companies have abruptly cut ties with the National Rifle Association as gun safety activists on Friday intensified calls for a boycott in the wake of last week's Florida high school massacre.
The social media-fueled campaign has led a range of corporations, from a major insurer to three car rental brands, to sever relationships with the gun rights advocacy group.
Amazon.com Inc and other online streaming platforms are also facing demands to drop the online video channel NRATV, featuring programming produced by the group.
Moms Demand Action for Gun Sense in America, founded after 20 first-graders were shot and killed at a school in Connecticut in December 2012, sent letters to Apple Inc, AT&T Inc , Amazon, Alphabet Inc's Google and Roku Inc on Friday, asking them to drop NRATV from their products. None of the companies immediately responded to requests for comment on the letters.
"We have been just disgusted by NRATV since its beginning," Shannon Watts, founder of the Moms Demand Action group, told Reuters. "It really propagates dangerous misinformation and inflammatory rhetoric. It tries to pit Americans against one another, all in an attempt to further their agenda of selling guns."
The U.S. Constitution's Second Amendment protects the right to bear arms. The NRA, which has long used campaign donations and effective lobbying to hold outsized political influence, argues that stricter gun control would erode individual rights. The group has not commented on companies cutting ties.
The question of gun control, and the NRA's role in opposing it, became the focus of national debate on Feb. 14, when Nikolas Cruz, a 19-year-old former student at Marjory Stoneman Douglas High School in Parkland, Florida, returned there and killed 17 people, mostly students, with a legally purchased AR-15 rifle, according to authorities.

The hashtag #BoycottNRA was the top trending topic on Twitter on Friday morning. The campaign is the latest effort by activists to deploy social media and use economic pressure to force change.
Similar drives helped convince Fox News to terminate television host Bill O'Reilly, after sponsors dropped his show in the wake of sexual harassment allegations, and the National Football League bowed to improve its handling of domestic violence accusations against players.

Moms Demand Action posted an online petition using the hashtag #DumpNRATV.
"To be affiliated with them, whether you are a company or a lawmaker, it is not going to pay off in the long run," said the Moms Demand Action founder Watts, signaling the start of a broader campaign. "Doing business with the NRA is clearly bad business."
Angry student survivors of the shooting have confronted politicians from state lawmakers to U.S. President Donald Trump himself, demanding stricter gun control laws.
In response, the NRA and Trump have suggested arming teachers who have received training to deter attackers, a proposal that has been met with skepticism by teachers unions and gun violence experts.
