With 50% of American women tuning in to regular season football games, the NFL is upping its girl game, running a 16-page advertising insert in Marie Claire. Called “The Savvy Girl’s Guide To Football,” it features actress Minka (“Friday Night Lights”) Kelly, and such articles as “Master The Lingo” and “Draft a fantasy A-Team.” It includes six pages of advertising for NFL apparel. Ads are also running in Vogue, Cosmopolitan and Us Weekly.
