Summary

  • Telenet’s December 1977 coverage figure described local access across 85 North American cities, not 85 cities full of active users or a measured share of households online.
  • The company was expanding on leased carrier facilities while reporting more than $8 million in losses and seeking public capital for its next locations.

Analysis

A city count can describe where a network offers an entry point without showing who uses it. In December 1977, William H. Jones’s account of Telenet’s share offering said that 85 North American cities gave local access to about 80% of the US population. The same report described most subscribers as corporations or government agencies using the network to connect terminals with computers inside their own organizations. Colleges, an insurer and a bank illustrated the service. The figure was not a count of subscribers, residential lines, traffic or people who had used the system. (The Washington Post, 22 December 1977)

The network itself joined two kinds of investment. Telenet supplied packet switches and the interfaces that connected terminals and host computers. For transmission between its centres, it leased high-speed lines from established carriers. Its 1974 company report described a value-added carrier that combined leased circuits with switching, speed and code conversion, diagnostics and billing. That source was promotional and often described intended service, but it makes the division of work visible: Telenet operated a data network without owning most of the long-distance transmission beneath it. (Telenet Report, Summer 1974)

The financing followed the same distinction. The Post reported 1975 revenue of $126,799 and $1.9 million for the first seven months of 1977; those periods are not comparable lengths. It also reported losses exceeding $8 million since inception. Telenet’s initial public offering was 625,000 shares at $9 each, after an earlier hoped-for range of $16–$20. Management expected revenue to support profit in 1979 and planned to use offering proceeds for more locations in 1978. That was a forecast and a funding plan, not a record of later results.

The city total is itself uncertain. A 1980 NIST report, citing Telenet’s 1977 prospectus, listed 81 cities and warned that its information needed direct verification. It does not explain how that count relates to the Post’s 85 North American cities. Both figures should be read as attributed snapshots, not an audited inventory. (NIST Technical Note 1104)

By April 1978, Telenet chairman Lawrence Roberts counted 187 network nodes, 79 switches and local dial service in 156 US cities. In December, the Post described operations in 170 US cities and 22 foreign countries, while reporting continued losses and a GTE purchase proposal that still needed approval. Telenet’s footprint had grown; the available reports do not show that standalone profitability had arrived.
