The Internet is driving the growth of a revolutionary commercial paradigm in which size and physical location are surrendering to ''virtuality,'' and in which businesses are facing unprecedented marketing challenges. With the meteoric rise to prominence of the World Wide Web, no manager can afford to be indifferent to this technological revolution, for the Web has dramatically--and globally--expanded customer options, putting uniquely competitive pressures on companies large and small.
