The Budweiser ad featuring a man and his Clydesdale horse has become the most shared Super Bowl 2013 ad so far, with over 1.5 million shares and 5.5 million views.
The figures have been reported by Unruly, who found that every 3.6 people who saw the Brotherhood ad shared it.
Dan Best, planning and international activation director at Unruly, said: "Budweiser's Super Bowl ad, Brotherhood, has really touched a nerve, becoming the third most shared Super Bowl ad of all time in just five days. So despite all the ads from autos brands, it's real horse power which won the day.
"Bearing in mind that the average Super Bowl ad attracts 55% of its shares a month after Super Sunday, Brotherhood certainly has the form to overtake The Force to become the most shared commercial of all time. The only thing that could hold it back is whether it boasts the same global appeal as The Force did.
"It's not surprising the ad is so popular, it's really taken on board the fact that ads which elicit the strongest, most positive emotions are the most shared. Brotherhood does this by using their extremely popular Clydesdale horses to tell a heart-warming tale of an enduring friendship, eliciting very strong feelings of warmth, nostalgia and happiness. The choice of Fleetwood Mac's iconic track Landslide is also a masterstroke."
