We keep a selection of magazines [National Geographic, Scientific American, Newsweek, anything except, maybe, women's magazines :)] on the den coffee table for anyone who wants to peruse them. Older kids and teenagers will pick these up while lolling around for "down time." I know this works because I read the periodicals on my parents' coffee table growing up.
Of course, it helps if the t.v. is off most of the time, but that's another subject!
