The Super Bowl Ad Fox Rejected
NBC also banned AshleyMadison.com from appearing during last year's game.
Fox has rejected an ad for AshleyMadison.com, an online dating service for those looking to have affairs.
The spot features porn star Savanna Samson in a bra and underwear.
The net says its Standards and Practices division "has deemed the Ashley Madison spot is not acceptable to air on FOX."
The company, whose slogan is "Life is short. Have an affair," was also banned by NBC from advertising during last year's Super Bowl.
