Some of the world’s largest brands are squaring off today in a high-stakes game of ... Monopoly. Well, kinda.To promote its new, brand-centric game, Monopoly Empire, Hasbro is hosting a Facebook “Battle of the Brands” featuring several of the companies featured in the game. The goal is to see which brand can get 5,000 Likes on its #BattleoftheBrands Facebook post first. Participating are Carnival Cruise Lines, Transformers, Chevrolet, Fender Guitar, Nestlé, Beats by Dre, eBay, X Games, Nerf, Ducati, Electronic Arts, JetBlue, Coca-Cola and Yahoo.As of this writing, Carnival had already blown past the 5,000-Like mark in a mere two hours, despite having just 2.2 million fans, a mere fraction of Coca-Cola’s 73.6 million. A few brands, namely Beats by Dre, JetBlue and Chevrolet, were past 2,000 Likes, while poor eBay and EA apparently forgot to participate altogether—or at least hadn’t posted anything two hours into the competition. Perhaps even sadder, Nestlé and Yahoo did participate but hadn't broken 200 Likes yet.While it may not be a true test of brand potency, today's challenge sure is a telling reminder that there's a big difference between having a lot of fans and knowing how to put them to use. After the jump, check out a fun gallery of branded images Monopoly created to tease the contest.
