A stochastic cellular automata model of new product diffusion is propo
sed. It is found that the growth for a given market potential can be d
etermined by a parameter that quantifies chance preferences of individ
uals for the product and can be estimated from field surveys. It is al
so found that the ''takeover time'' in a given seed region is almost i
ndependent of the number of innovators. The results suggest possible s
trategies for the successful introduction of a new product.
