Do books still have that type of impact on young people?
Yes. Rowling's main goal with Harry Potter was tackling racism, genocide and tribalism. Whatever else some may say of her skills, she managed that I think. An entire generation of kids grew up with that series whose impact was global, and more will do so probably for quite some time. Children are still reading Narnia. It's not converting them to Christians, but it is teaching them something about bravery, loyalty and compassion while giving them a fantastic world. There is more deliberately Christian oriented fiction that offers positive support for Christian teens.
Will Grayson, Will Grayson and Boy Meets Boy are two recent major YA bestsellers that have opened up dialogue about gay teens. And there is an increase in gay/lesbian stories rather than just the default of straight characters. That has an impact.
The tiny amount of non-white fiction has an impact, and the fact that it's still a tiny amount has unfortunately a negative impact. Hunger Games has very apt commentary on our current society. Environmentalism in YA and children's has been a part of the youth environmentalism movement. The Sisterhood of the Traveling Pants is about female empowerment, growing up and sisterhood. Westerfeld's Uglies series also is SF packed with social commentary. The American Girl series does offer a somewhat more accurate history lesson that also shows that females were not invisible in history. 39 Clues teaches them puzzles, and so on.
And Judy Blume, well Judy Blume has had a major impact for about forty years in several categories. YA can tackle about every major issue you can think of and usually does. YA and children's authors often have very low status in the eyes of adults. But just about every YA author will tell you that he or she has had at least one, if not several fan letters that say their book saved a kid's life.
And when those books get on screen, the impact enormously widens. Braveheart was not based on a book. But other works are -- Bridge to Terabithia, for instance. How to Train Your Dragon. When those movies come out, the sales of the book jump to major levels as kids seek out the books. And we have ample evidence that they bring in new readers who then browse (because that is what fiction readers do,) which is how children's doubled in size and the YA area quadrupled in size in the wake of the Harry Potter movies. And once the movies are out of the theaters, adults may forget about them, but children don't because parents buy the DVD's and they grow up with them. There are toys, games, etc. And a book thus becomes a significant part of the culture. For teens, the product side is actually somewhat less, and more likely to involve clothing. But the books launch them into adult fiction -- the greatest impact of a hit YA novel? We get an uptick in readers who then stay readers. So the partnership between kids/YA fiction and Hollywood right now is pretty important, just as the partnership between SF authors and Hollywood in the 1960's and 1970's was pretty important to SF and helped SF have an impact on culture too.
