Hewson Consultants Ltd. was founded by Andrew Hewson in 1980, and stationed in Abingdon, Oxfordshire in Britain. In its earliest years it was actually a book publisher. It started producing and publishing games for the Spectrum system in the midst of 1982, but later expanded to other systems as well.
Hewson specialized in action games, and particularly platform games. A good example of this would be Stormlord.
However, the company ran into financial trouble in 1991, and so 21st Century Entertainment Ltd. was born. And this time, the focus was on the very popular Pinball genre.
