In 1989, three Montana telephone cooperatives established Montana Directories, a company that began with the publishing of six rural telephone books. The demand for the company's publishing services grew, and in 1994 Northern Directory Publishing (NDP) was founded to meet that demand. The newly formed company produced 20 directories in four states. Soon after being incorporated, NDP acquired two local printing firms and changed its name to NorthWinds Publishing and Printing, providing both publishing and printing services to rural telephone companies. In 2006, the printing facility was sold to Gannett Inc., and the company focus was once again on telephone directory publishing. Today, NDP is a national company publishing over 50 directories for a growing number of telephone companies stretching from the state of Washington to Florida and Maine.
