"I wrote 87 Goosebumps books. That's a lot of books for a human, isn't it? None of us expected what happened with Goosebumps. We started it in 1992, and by 1994, I was turning out a Goosebumps a month, and it was doing okay for a while. And then it just took off like nothing we'd ever seen. It took off all over the world – not through advertising, hype, or promotions – but just kids telling kids. There's some kind of secret kids network out there. Just kids telling kids about it, and this thing grew everywhere. It was in 28 languages. At one point, after a couple years, we were selling 4 million Goosebumps books a month."
