Will large multinationals lose the advantages of size, while small start-ups leverage the technology and be-come big players internationally? The authors discuss the different opportunities and chal-lenges that the Internet offers to large and small companies worldwide. They examine the impact on global markets and new product development, the advantages of an intranet for large corporations, and the need for foreign government support and cooperation.
