Since the 18th century, people have been fascinated by the idea of machines that could play chess against humans. With the advent of the digital electronic computer in the mid-20th century, that dream finally became feasible. What followed was six decades of intense development in the field of computer chess, from research projects to commercial products. Over that period, computers grew from playing only a limited subset of chess to beating the World Chess Champion in a six-game match. Today, a worldwide computer network (the Internet) facilitates play between humans all over the world.
Clearly, computer chess has come a long way. Let's take a compressed look at some key moments in its evolution over the years.
