At the age of nine, Mark Rappaport invented his first toy. Even though it wasn't accepted by Mattel when his father presented it to them, this didn't deter Rappaport from trying again and again. Now in his 40's, he had invented dozens of toys for Oddz On, Just Toys, Sport Fun and Hasbro, with sales reaching more than $100 million. His latest endeavor, Marky Sparky Toys, marks the first time he is manufacturing and marketing his own product.
