"Online retail sales have risen from nothing to about $20 billion. Business-to-business transactions—that B2B thing—have grown to $109 billion. By 2003, Forrester Research estimates, online retail sales will grow to $144 billion, and B2B business e-commerce will jump to $1.3 trillion. (That's just in the United States, folks.)"
