About 3m people a day look at Cosmopolitan's channel on Snapchat Discover

"Most millennials probably don’t know who Helen Gurley Brown is, but the Cosmopolitan brand Brown built is resonating with the young set — on Snapchat, at least.
Cosmopolitan says it’s averaging 3 million viewers a day on Snapchat Discover, a milestone that could appeal to some advertisers who wonder whether these media channels on the messaging app are desirable places to run their spots. Cosmo, which has been a Discover partner since the service launched in January, has seen traffic go from about 1.8 million a day to 3 million viewers since the summer, according to Kate Lewis, vp and editorial director of digital at Hearst Magazines, which owns Cosmo.
When asked whether the app is worth the editorial effort, she replied: “Oh my god yes. It’s been amazing, and we have about 3 million people a day on the Discover platform.”"
