US Robotics: Модемдер тарихы және дамуы

Business enterprise

U. S. Robotics Corporation, often called USR, is a company that produces USRobotics computer modems and related products. Its initial marketing was aimed at bulletin board systems, where its high speed HST protocol made FidoNet transfers much faster, and thus less costly. During the 1990s it became a major consumer brand with its Sportster line. The company had a reputation for high quality and support for the latest communications standards as they emerged, notably in its V. Everything line, released in 1996. With the reduced usage of voiceband modems in North America in the early 21st century, USR began branching out into new markets. The company purchased Palm, Inc. for its Pilot PDA, but was itself purchased by 3Com soon after. 3Com spun off USR again in 2000, keeping Palm and returning USR to the now much smaller modem market. After 2004 the company is formally known as USR. USR is now a division of UNICOM Global, and is one of the few providers left in the modem market today. The division employs about 125 people worldwide.

USR was founded in 1976 in Chicago, Illinois (and later moved to Skokie, Illinois), by a group of entrepreneurs, including Casey Cowell, who served as CEO for most of the company's history, and Paul Collard who designed modems into the mid 1980s. The company name is a reference to the fictional company U. S. Robots and Mechanical Men which featured prominently in the works of Isaac Asimov. The company has stated it was named as an homage to Asimov because in his science fiction works U. S. Robots eventually became "the greatest company in the known galaxy", and USR appeared in I, Robot (2004) as the fictional company itself. In its early years (circa 1980), USR was a reseller of computers, terminals and modems. At the time, commonly available modems ran at 300 bit/s, but 1200 bit/s using the mutually incompatible Bell 212A and V.22 standards were available at much higher price points. Even in 1983, 300 bit/s remained the most common speed. In 1984, the V.22bis standard provided 2400 bit/s service, but these remained high cost devices. USR sold its first modem, the Courier, to corporate customers starting in 1979. In 1984, the breakup of AT&T greatly lowered the cost of the testing needed for connection to the telephone network, which led to lower prices and wider use of modems. They began offering the Courier to the public in 1984. In 1986, USR introduced their Courier HST, short for "high speed transfer". Using trellis encoding, HST provided 9,600 bit/s speeds, leapfrogging the standards efforts and offering four times the performance for about twice the price of a 2400 bit/s model. In 1989 HST was expanded to 14.4 kbit/s, 16.8 kbit/s in 1992, The Courier modems remained a favorite in the BBS and emerging Internet service provider world, where they were known to run without problems for extended periods of time (although the initial large scale deployment of Courier modems in the CompuServe network uncovered a serious bug, which would cause the modems to crash and stop answering calls under high call volumes). A similar situation emerged a few years later when the 56 kbit/s V.90 standard was first being proposed. USR developed its own 56k standard known as X2, while a consortium of other companies introduced its own K56flex. In contrast to the success of HST, neither X2 nor K56flex saw any real market uptake, as it was clear they would soon be followed by V.90 modems. After the introduction of V.90, USR abandoned support for X2. In a further effort to reduce the retail price of its modems, USR also marketed a Winmodem that used software running on the host computer to perform some of the modem functions. it shipped with only V. FC support, because V.34 had not been released. A free V.34 firmware upgrade was made available later via FidoNet, as well as the Internet. USR then surprised many early Courier V. Everything modem owners with a limited time free offer of an X2 firmware upgrade, which added 56K speed capability. Finally, USR released a V.90 upgrade that was compatible with X2 upgraded Courier V. Everything modems. Even the 1994 hardware released pre V.34 was fully V.90 upgradeable without hardware modification. There was a licensing key needed for some Courier V. Everything V.90 flash upgrades. The firmware could be loaded onto the modem, but it would work in "degraded" V.34 mode. After paying a fee, and having the modem dial USR, a license key was installed that enabled the V.90 functions.

USR acquired Palm, Inc. in 1995 and subsequently merged with 3Com Corporation in June 1997. It was then recreated as a spin off of 3Com in June 2000, assuming 3Com's entire client modem business except for the Palm related portion, which itself had been spun off with Palm three months earlier. Other portions of the original USR remained part of 3Com as the CommWorks Corporation. USR then quickly built up its device portfolio, including not only traditional dial up modems, but also wired and wireless networking components. USR was acquired by private equity firm Platinum Equity for an undisclosed amount of cash in 2005, believed to be between US$30 million and US$50 million. By 2010 the company was focused only on the traditional modem business. In 2013, USR was acquired by UNICOM Global.
