Oreos are popular. Svati Kirsten Narula looked at just how popular:

• $3.28 billion worth of Oreos were sold in 2014. This is triple the amount made by the next highest selling cookie in the world.
• Their popularity is in part due to the cookie’s versatility. Deep fried Oreos are now fairly common at state fairs, and sports stadiums are experimenting with Oreo churros.
• There are a myriad ways of eating them too – from twisting them apart, to dipping them in milk, to licking the cream off.
• The company behind them has a smart social media strategy. There are more people who like Oreos on Facebook than there are people who like Starbucks.
• Its makers dares to experiment. You can get Red Velvet Oreos, white fudge ones, peanut butter cup ones, cool mint ones, and even root beer ones.
• They also tailor to local tastes. In China you can get green tea Oreos and in Mexico there is a “Trio Chocolate” version that has the standard crème filling, and then different creams lining each of the cookies.
