In 2013, "Forbes" published a story titled "Here's How You Buy Your Way Onto "The New York Times" Bestsellers List." The article discusses how ResultSource, a San Diego-based marketing consultancy, specializes in ensuring books make a bestseller list, even guaranteeing a No. 1 spot for those willing to pay enough. "The New York Times" was informed of this practice and responded: ""The New York Times" comprehensively tracks and tabulates the weekly unit sales of all titles reported by book retailers as their general interest bestsellers. We will not comment beyond our methodology on the other questions." "The New York Times" did not alert its readers to this, unlike "The Wall Street Journal," which admitted that books had landed on its bestseller list due to ResultSource's campaign. Soren Kaplan, the source who admitted he had paid ResultSource to land his book, "Leapfrogging", on "The Wall Street Journal"s bestseller list, revealed the methodology on his blog; he posted: "If I could obtain bulk orders before Leapfrogging was released, ResultSource would purchase the books on my behalf using their tried-and-true formula. Three thousand books sold would get me on "The Wall Street Journal" bestseller list. Eleven thousand would secure a spot on the biggest prize of them all, "The New York Times" list."
