Do you think the Harry Potter books turned more kids into readers?

Yes. Temporarily any way. My girls and I are voracious readers. Chris never cared for it.
I walked in the living room one day, and he was curled up in my reading spot, spell bound by Harry Potter!!!!!

I know a bunch of kids that really didn’t like reading before HP, then became pretty intense genre readers. First fantasy, the soft SF, then harder SF. Recently, a 25 year old friend of mine, who had hated reading until then, was just so excited about Andy Weir’s newest, which is a pretty far cry from the world of Hogwarts.

I was already a reader by the time I first read Harry Potter (the first book was released in the U.S. in 1998 when I was 7, though I didn’t read it until three years later) but I know from friends and other anecdotes that it did turn many kids into readers. (At the time I was also reading A Series of Unfortunate Events and His Dark Materials, all of which helped cement my love of reading).

It helped turn my children into readers.

Absolutely.
