Although Konami Corporation's history as being part of the casino slot machine industry is far shorter than the 75 year history of Bally Technologies, its emergence onto the scene is one of note. Konami Corporation is a Japanese game development company that entered the traditional slot machine industry in the late 1990s. Konami's beginnings date back to the early 1970s when the company was predominately involved in the rental and repair of music jukeboxes. Although the company is known for the software game titles it created for Nintendo in the 1980s—Skate or Die, Contra, Metal Gear and Castlevania. Konami Corporation's success in its software development and gaming products allowed it to dive full bore into the slot machine industry. An exercise that most smaller companies can not do because of the enormous barriers to entry—licensing costs, technological understanding, etc.
