The letters "SPSS" mean something different today than they did when the product was conceived. When SPSS was founded in 1968, SPSS Chairman of the Board Norman H. Nie collaborated with C. Hadlai (Tex) Hull and Dale Bent, two of his fellow Stanford University graduate students, and developed the first SPSS program. They named it "Statistical Package for the Social Sciences," or "SPSS." As the "package" has grown into a multinational product serving a wide variety of users and the business has evolved from its academic roots to becoming a leading enterprise analytical solutions provider today, we simply use the "SPSS Inc." for the company and "SPSS" for the original product.
Because we are a worldwide organization with many software products, we offer a variety of pricing and licensing programs, including site licenses and network licenses. Factors such as exchange rate fluctuations, customs duties and partnering agreements affect local pricing and licensing programs. In addition, training and support programs vary by country. In order to reduce confusion, we do not list pricing programs on our site. To learn which local program best suits you, please contact your local SPSS office or distributor.
