The costume from Netflix's hit 'Stranger Things' that's blowing up this Halloween

Your head has to be in the sand if you haven't recognized that Eleven, the powerful little girl with a healthy appetite for Eggos, is the most popular "Stranger Things" Halloween costume.

But Business Insider wanted to see just how popular the character from Netflix's show really is this Halloween. To find out, we partnered with technology and marketing platform Amobee.

It analyzed real-time content consumption across the internet, video, social, and mobile in the week leading up to Halloween (October 23-to-31) to determine which "Stranger Things" characters were generating the most engagement.

And what Amobee found supports the popular sentiment. Eleven is the most popular "Stranger Things" topic of discussion in the week leading up to Halloween and in discussions involving costumes in the same period. The last time discussion about Eleven costumes peaked was during last month's New York Comic Con.
