A HISTORY OF COMPUTER COMMUNICATIONS
The coming into existence of new markets is seldom predictable or simply the actions of corporations innovating products for sale. If there are no buyers, the exchange essential to markets fails to form. However, markets require more than buyers and sellers. They also require the institutional organizations that create and enforce the rules that make the existence of such needed forms as money, contracts, insurance, public financial markets, venture capital, the legal system, and of particular importance to computer communication markets, standards possible. The focus of attention in this reconstruction is the emergence of start-up corporations. In each of th.e three new market sectors observed – Data Communications, Networking and Internetworking – start-ups forced the action and dominated eventual market outcomes. But for each new market, there were existing firms; in some cases the existing firms were gigantic corporations in others they were the start-ups of an earlier to form market. How start-ups responded to the formation of new markets will be of special interest in this reconstruction. The importance of buyers will be treated in aggregate and statistically, thus more a backdrop to the decisions and actions of entrepreneurs and engineers forming start-ups.
Additional organizations necessary to the understanding of the history of Computer Communications are government agencies, such as the Defense Advanced Projects Agency (DARPA) or the Justice Department, non-government organizations, such as Universities or the Independent Data Communications Manufacturers Association (IDCMA), and, of particular interest, standards-making organizations such as the Institute of Electrical and Electronics Engineers (IEEE) or the International Standards Organization (OSI).
Start-ups begin when an entrepreneur decides to act on the vision he or she has for how new products can better serve users' needs. In the communication start-ups of this history, the entrepreneurs are invariably engineers. Having decided to act, the entrepreneur faces three essential challenges: recruit the core members of the founding team, reduce the vision to a business plan, and raise the needed capital. Once successful, the start-up has entered the Collective stage. The essential task of the Collective stage is to create working product. The Competitive stage comes next and lasts until the firm has achieved profitability. It is around this time that the firm has the opportunity to access the public capital markets by launching its Initial Public Offering (IPO). Few firms reach this stage, but those that do next enter the Persistent stage and must not only continually improve their products but must make the risky move into new technology-based products. Again, only a small number of firms can attain the Adaptive stage with the promise of becoming really substantial firms. The unique challenges of each stage will be observed most closely in two firms of each market secor. But to understand the coalesence of the inital surge of start-ups into market order requires also observing some of the history of closely competitive firms. Lastly, other firms that have some impact on the principal firms will also be mentioned. While the narrative schema of stages helps order the histories, each firm's history can vary from the general. The start-ups of every market sector become existing firms to succeeding markets.

For every market sector there already exist firms that offer slightly similar products, or are logical firms to offer products, to those that will come to define the new market. For example, to all three Computer Communication markets, computer as well as telecommunication firms fit the definition of existing firms. However, only a few of them successfully enter one of the Computer Communication markets. Another example of existing firms to Data Communications were defense contractors building modems or multiplexers under military contracts. A third example of existing firms are the Data Communication start-ups serving as existing firms to both Networking and Internetworking and the start-ups of Networking serving as existing firms to Internetworking. While there are generally many existing firms, only a few will be highlighted.

The U.S. Government played crucial roles in the historu of Computer Communivations. The Defense Department contracted to buy data communication products when they were not available commercially and through the Advanced Research Projects Agency (ARPA) they funded both the creation of the Arpanet and the continuing work to create the TCP/IP networking protocols. The Justice Department forced the breakup of AT&T. The Federal Communications Commission (FCC) overturned a long standing practice of protecting AT&T's refusal to allow foreign attachments with the Carterfone decision and participated in the eventual breakup of AT&T through its Computer Inquiry decisions. The National Bureau of Standards played important roles in the advancement of networking technologies and the establishment of netwokring standards.
There exist a vast array of ogranizations and institutions that are neither direct market competitors nor governmental organizations that contribute to the history of Computer Communications. The following are examples of organizations and institutions that co-evolved with Computer Communications: venture capital and public Initial Pulic Offering markets for high technology companies; emerged as a consequence of Computer Commuincations: Independent Data Communications Manufacturers Association (IDCMA), the Institute of Electrical and Electronics Engineers Committee 002 (IEEE Committeee 802) and a collaboration of Digital Corporation, Intel and Xerox (DIX); or were activities of existing organizations tailored to the needs of Computer Communicaitons: trade shows (Enterprise Networking Event (ENE) and Interop Trade Show), investor conferences (the Alex Brown & Sons Conference: March 1983), and market research reports of either investment banks (Alex. Brown & Sons or Salomon Brothers Inc.) or market research firms (Dataquest or Datapro Research).

"Entrepreneurial Capitalism:
A
History of Computer Communications"
By James Pelkey
An overview of the book schema is presented in the Introduction. It is organized by these three dominant
co-evolving market sectors and standards making.
One can explore a market sector from vision to adaptation - below.
