We’ve all come to accept the fact that there’s no escaping the Kardashian-Jenner clan.

From TV shows to mobile apps to fashion lines, it seems the polarizing family has infiltrated every area of pop culture. And we really can’t blame them. Anything they attach their names or faces to tends to be very successful, and very profitable. But according to a recent report by WWD, there is one place where the Kardashian-Jenners aren't killing it: on magazine covers.

Using data collected by Alliance for Audited, WWD found that when magazines featured members of the family on their covers, they experienced a decline in copy sales. Pretty shocking considering the slew of covers they landed this year.

For example, during the first half of 2015, Cosmopolitan’s single-copy sales averaged 531,086. When Kendall Jenner took the cover for the magazine’s February issue, it only sold 495,423. Clearly it wasn't a success, but it did out-sell the November issue, which featured all the Kardashian-Jenner daughters along with their mother, Kris. That issue only sold 436,500 copies.

The article goes on to provide additional data from magazines like GQ, Glamour, and Vanity Fair, which all experienced sales declines when they put members of the family on the cover; however, it’s important to note that there were a few exceptions: Rolling Stone, Women’s Health, and Teen Vogue surpassed their averages when they had Kardashian-Jenner cover stars—reminding everyone the family still has a large and loyal following.
