was involved early in making astrological software for microcomputers available to the general public in the late 1970s. In 1978, Erlewine founded Matrix Software, and in 1980 he published a book with all the algorithms and data required for owners of microcomputers to make their own complete astrological programs. At first, astrology software was opposed by American astrologers who did not approve of computers in their field. However, acceptance grew as it became clear how more efficient and profitable such software could be. A few hundred fixed-purpose astrology computers were made, one of which was used by Nancy Reagan's astrologer beginning in about 1981. Astrology software has been made available in the
