People are calling for a boycott of the Hallmark Channel after they pulled an ad from wedding planning company Zola that featured a same-sex couple.

Zola was appalled by the channel's decision and issued a statement to Buzzfeed News, condemning the action.

"The only difference between the commercials that were flagged and the ones that were approved was that the commercials that did not meet Hallmark's standards included a lesbian couple kissing," Mike Chi, Zola's chief marketing officer, said in a statement.

Conservative group One Million Moms said that they had received several complaints after the ad, which showed a lesbian couple kissing, aired.

"The Hallmark Channel has always been known for its family friendly movies," the group wrote. "Even its commercials are usually safe for family viewing. But unfortunately, that is not the case anymore."

The group later claimed that they had "personally spoke to" the CEO of Crown Media Family Networks, Bill Abbott, who informed them that they would be pulling the commercial.

"He reported the advertisement aired in error, but he was informed about it after hearing from concerned 1MM supporters. Way to go!" the group wrote.

"The debate surrounding these commercials on all sides was distracting from the purpose of our network, which is to provide entertainment value," Molly Biwer, senior vice president for public affairs and communications at Hallmark, said in a statement to AP.

She continued: "The Hallmark brand is never going to be divisive. We don't want to generate controversy, we've tried very hard to stay out of it ... we just felt it was in the best interest of the brand to pull them and not continue to generate controversy."

The president and CEO of Hallmark Cards, Mike Perry, apologized on social media for the move.

"The Crown Media team has been agonizing over this decision as we've seen the hurt it has unintentionally caused. Said simply, they believe this was the wrong decision," he said. "We are truly sorry for the hurt and disappointment this has caused."

The ad has since been reinstated.
