Wafer Origins

"Wait, what's the difference between Vanilla and Nilla?"

According to the ever so trusted wikipedia:

"The recipe for vanilla wafers or sugar wafers was first invented in the late 19th century by German confectioner Gustav A. Mayer on Staten Island. He sold his recipe to Nabisco, and Nabisco began to produce the biscuits under the name Vanilla Wafers in 1898. By the 1940s, Vanilla Wafers had become a major ingredient in the Southern cuisine staple banana pudding, and Nabisco began printing a banana pudding recipe on the Vanilla Wafers box. The name of the product was not changed to "Nilla Wafers" until 1967.
In 2013 the brand launched an advertising campaign on Facebook and other social media websites targeted at mothers. It was noted by the New York Times for being unique because Mondelez International, the company that Kraft created to own the brand, decided to spend all of its advertising dollars on social media rather than a combination of advertising platforms. The campaign resulted in a 9% increase in sales for Nilla. Nabisco had previously used other marketing techniques to promote the brand, including in-person events such as sponsoring banana pudding pie eating contests at amusement parks."
