Microcomputers first appeared on the commercial marketplace in 1976. Since then, an estimated 40 million microcomputers have been sold and more are being sold each day. A survey conducted in 1982 found that 13 percent of American cities owned microcomputers and that 35 percent planned to buy one or more microcomputers within two years (Norris and Webb, 1984). A follow-up survey conducted three years later found that between 75 percent and 90 percent of city governments owned microcomputers (Scoggins, 1986).
