Using a sample of 130 industrial businesses,,ve found a substantial positive effect of the use of the Internet on sales management activities, market-oriented product management activities, and sales performance and efficiency. The results of this study also stress the central role of the salesforce in the successful implementation of the Internet marketing strategies within organizations. (C) 2000 Elsevier Science Inc.
