The one-minute ad watched by more than 100 million viewers featured King's famous "The Drum Major Instinct" sermon he gave at Ebenezer Baptist Church in Atlanta, Georgia, just two months before he was assassinated.
But the company that manages the former civil rights leader's intellectual property, run by his son, Dexter King, issued a statement Monday morning saying it had approved the ad.
"We found that the overall message of the ad embodied Dr. King's philosophy that true greatness is achieved by serving others. Thus we decided to be a part of Ram's 'Built To Serve' Super Bowl program," the firm, Intellectual Properties Management, said in its statement.
Besides promoting Dodge Ram pickup trucks, the ad was meant to publicize Ram Nation, the car company's campaign to encourage volunteerism at food pantries, clean-up programs and other do-good projects in communities across the country.
The ad begins with the words "Dr. Martin Luther King Jr." and gives the date Feb. 4, 1968, day 50 years ago to the day after when King gave his sermon.
As music plays, and King's soaring voice is heard: "If you want to be important--wonderful. If you want to be recognized--wonderful. If you want to be great--wonderful."
A black Dodge Ram truck appears in the commercial plowing through the mud as King reaches the apex of his sermon, saying, "But recognize that he who is greatest among you shall be your servant. That's a new definition of greatness."
Images of Americans show throughout the commercial, ranging from horse wranglers in the West to fishermen, teachers and Marines.
The ad was roundly bashed on social media with people calling it "tasteless" and "tone deaf."
In a Twitter post, actress Justine Bateman wrote, "A Martin Luther King Jr speech to sell @Dodge Ram trucks? Totally offensive. #mlk."
New York Times columnist Charles Blow, also took to Twitter, writing, "The blatant commodification of black culture, black struggle and black pain illustrates perfectly how America is perfectly willing to exploit blackness but perfectly incapable of honoring it. #DodgeRam #MLK."
"It is 50 years to the day that Dr. Martin Luther King Jr. gave such a tremendous speech about the value of service," the company said. "Ram was honored to have the privilege of working with the Estate of Martin Luther King Jr. to celebrate those words during the largest TV viewing event annually. We worked closely with the representatives of the Martin Luther King Jr. estate to receive the necessary approvals and estate representatives were a very important part of the creative process every step of the way."
"You could come out two sides on that and say, 'It's quite exploitative,' [and] on the other hand, you could say, 'Well, just the more people that hear his voice, we're better for this.'"
Deutch added that in today's world, the commercial will most likely be forgotten.
"I always wonder at the end of the day do people remember?" he said. "Are they going to remember? 'OK, I remember there was a Martin Luther King ad, but who was it for? I remember there was an ad about first responders, but who was it for?'"
