Advertising campaigns in which one company slams a competitor are nothing new: There's the coffee war between Starbucks and Dunkin' Donuts, and the burger battle of McDonald's versus Burger King. The latest companies to publicly duke it out? Domino's Pizza and Subway. According to a taste test conducted and promoted by Domino's, consumers prefer their baked sandwiches over Subway's sandwiches by a two-to-one ratio. Subway quickly responded to the claims by sending Domino's a letter telling the pizza chain to stop airing the commercials. Then last week on national television, Domino's president David Brandon burned the letter. Subway has yet to comment on Domino's aggressive advertisement, and a lawsuit is likely.

After tasting Domino's baked sandwiches, I find it hard to believe they could beat out Subway's sandwiches in a blind taste test. I also think the behavior in the video is childish and immature. Burning a letter? It doesn't necessarily make me want to run to the nearest Domino's for a sandwich. Watch the video below and tell me what you think. Whose sandwiches do you prefer?
