In 1994, Christoph Bochinger published his study of the New Age in Germany, ""New Age" und moderne Religion". This was followed by Michael York's sociological study in 1995 and Richard Kyle's U.S.-focused work in 1995. In 1996, Paul Heelas published a sociological study of the movement in Britain, being the first to discuss its relationship with business. That same year, Wouter Hanegraaff published "New Age Religion and Western Culture", a historical analysis of New Age texts; Hammer later described it as having "a well-deserved reputation as the standard reference work on the New Age". Most of these early studies were based on a textual analysis of New Age publications, rather than on an ethnographic analysis of its practitioners.
