Business model changes a Xerox Alto. Xerox changed its business model in the 70s and 80s when the patent expirations eliminated the exclusivity of copying technology and diversification plans did not work. Many technologies developed especially in the Parc were ignored by Xerox and became the products of other companies, such as Ethernet, the WIMP interface, and personal computers. Plans to enter the PC market were destroyed by bad timing (for example, to launch a CP / M, 8 bits, the Xerox 820, when IBM put its PC about later). Similarly, Xerox developed a line of advanced typewriters just as they began to lose ground by the process of computer-based texts. Xerox invented laser printing, which became a multimillion dollar business for the company that still continues.Meanwhile, the manufacturing costs of the company were much higher than their Japanese competitors, the quality of design and manufacturing were questionable, and its internal culture had become problematic. The company was revived in the 80 and 90, improving the quality of their designs and redesigning its product line. The development of digital copiers in the 90’s and rebuild their range of products (primarily laser printers with built-in scanners that could be linked to computer networks) again gave Xerox a technical advantage over its competitors. Xerox worked to turn your product into a service, providing everything a “service of documents” to other companies, including supply, maintenance, configuration and user support. To reinforce this image the company introduced a corporate symbol, “The Document Company ” logo on its main and introduced a “digital X ” red. The “digital X” symbolized the transition of documents between the world of paper and digital.In 2005, to emphasize its strength and leadership in document services, the company abandoned the “digital X” and changed the corporate symbol to include mentions of technology services and consulting. To improve its position in the office printing market, bought the Tektronix printer division in 2000.
