USRobotics

Won three times with proprietary protocols, and gave up all three the moment a standard arrived.

Casey Cowell and four partners founded U.S. Robotics in a garage in Skokie, Illinois in 1976, naming it after the fictional company in Asimov's robot stories. The first modem shipped in 1979, and the business only opened to the general public after the AT&T breakup in 1984 made it legal for anyone to attach equipment to the telephone network.

**The two product lines are the story, and the relationship between them is better than either.** The Courier was built for bulletin board operators and businesses: rugged, remote-diagnosable, and using an upgradeable digital signal processor, so a Courier bought in 1994 as V.34 Ready shipped speaking V.FC because V.34 had not been finished yet, and was upgraded in the field when it was. That is why the line was eventually called V.Everything. The Sportster, launched in 1991, was the consumer line, and by the mid-1990s a 28.8 model sold for around $149.

**They shared a motherboard.** On certain 14.4 Sportsters, a sequence of AT commands would enable the faster 16.8 HST mode the Couriers were sold for. The hardware was the same; the difference between the consumer modem and the professional one was firmware and price. **Segmentation by software rather than silicon is now so normal it has a name, and this is one of the places it was learned.**

**The company's actual pattern is proprietary-then-standard, three times over.** HST was USR's own high-speed protocol, and it worked: if the board you dialled had a Courier, transfers ran faster than anyone else could manage, which is why HST spread through the bulletin board world and made FidoNet mail runs bearable. Then V.32bis arrived and HST stopped mattering. Years later the same play ran again with x2 against a rival consortium's K56flex, and neither won, because everybody could see V.90 coming. USR dropped x2 when it arrived.

**That is worth stating plainly, because it cuts against a thread this site returns to often.** Elsewhere the timeline records neutrality and openness paying off - carrier-neutral exchanges, vendor-neutral certification, protocols that stayed open and became infrastructure. USRobotics did the opposite and it worked repeatedly: a proprietary protocol bought real advantage for real years. **What it did not buy was permanence.** Every time a standard arrived, the advantage evaporated, and the company was sensible enough to stop defending it.

Scale followed the Sportster. Revenue was $889M in 1995 and $1.98B in the year to September 1996, a 122 per cent increase. The company bought Palm in 1995, acquiring the PalmPilot, and was itself acquired by 3Com in June 1997. It was later spun back out, moved to Schaumburg, Illinois, and now belongs to UNICOM Global.

One detail from the operators' side deserves recording: the first large-scale Courier deployment on CompuServe's network uncovered a bug that crashed the modems and stopped them answering calls under heavy call volume. **The most reliable modem on the market found its limit the way everything does - at a scale nobody had tested.**
