Few will argue that Games Workshop shouldn't be added to the list of most successful game companies. They are most well known for their Warhammer 40K and Warhammer Fantasy lines, but they have produced numerous smaller games over their history. From their beginnings in 1975, Games Workshop has seen significant changes to its business model. First it made game boards and a little later it became a publisher of 3rd party content. Their next step was to found citadel miniatures and they entered the market of producing miniatures for role playing and tabletop games. During the 80's, the properties of Warhammer 40K and Warhammer Fantasy were born. In the 90's the company refocused on these core lines and started opening retail stores. As GW enters it's 35th year, it has expanded to be a household name for gamers and many non-gamers thanks to its popular video games.
