Newsstand sales of U.S. magazines fell 6.3 per cent in the first half of 2008, an industry group said Monday, as rising gas and food costs led consumers to cut back on non-essential spending.

Most top titles, including best-selling Cosmopolitan and O, The Oprah Magazine, had sharp declines. Of the top 10 sellers, only People, the entertainment news magazine, and In Style posted gains.
