Appendix B

Transfers of Ideas and People and Other
Impacts Since 2003 Added to
Figure 1

Table B.1 gives some examples of the many transfers of ideas and people and other impacts that occurred as the fields of computing and communications progressed, and it provides annotation for events depicted by arrows in Figure 1. It is not meant to be a comprehensive description of the history of the research in any of the areas listed.
