Classical, CPU-based architecture of early Cisco devices coupled with flexibility of operating system IOS allowed for keeping up with evolving technology needs by means of frequent software upgrades. Īlthough Cisco was not the first company to develop and sell dedicated network nodes, it was one of the first to sell commercially successful routers supporting multiple network protocols. Upon hearing the news, her husband Bosack resigned in protest. On February 16, 1990, Cisco Systems went public with a market capitalization of $224 million, and was listed on the NASDAQ stock exchange. The logo is intended to depict the two towers of the Golden Gate Bridge. The name "Cisco" was derived from the city name San Francisco, which is why the company's engineers insisted on using the lower case "cisco" in its early years. In 1988, John Morgridge was appointed CEO. The company's first CEO was Bill Graves, who held the position from 1987 to 1988. In addition to Bosack, Lerner, Lougheed, Greg Satz (a programmer), and Richard Troiano (who handled sales), completed the early Cisco team. In 1987, Stanford licensed the router software and two computer boards to Cisco. On July 11, 1986, Bosack and Lougheed were forced to resign from Stanford and the university contemplated filing criminal complaints against Cisco and its founders for the theft of its software, hardware designs, and other intellectual properties. They adapted Yeager's software into what became the foundation for Cisco IOS, despite Yeager's claims that he had been denied permission to sell the Blue Box commercially. In 1985, Bosack and Stanford employee Kirk Lougheed began a project to formally network Stanford's campus. Due to the underlying architecture, and its ability to scale well, Yeager's well-designed invention became a key to Cisco's early success. The Blue Box used circuitry made by Andy Bechtolsheim, and software that was originally written at Stanford by research engineer William Yeager. In the early 1980s students and staff at Stanford, including Bosack, used technology on the campus to link all of the school's computer systems to talk to one another, creating a box that functioned as a multiprotocol router called the "Blue Box". Ĭisco's initial product has roots in Stanford University's campus technology. Bosack was in charge of the Stanford University computer science department's computers. Lerner was the director of computer facilities for the Stanford University Graduate School of Business. History 1984–1995: Origins and initial growth Ĭisco's first router, the Advanced Gateway Server (AGS) router (1986)Ĭisco Systems was founded in December 1984 by Sandy Lerner along with her husband Leonard Bosack. LinkedIn and Glassdoor also ranked Cisco as a top place to work in 2021 and recent years. In 2021, Fortune ranked Cisco number one for the second year on their annual list of the 100 Best Companies to Work For based on employee satisfaction surveying.
Ĭisco stock (CSCO) was added to the Dow Jones Industrial Average on June 8, 2009, and is also included in the S&P 500 Index, the Russell 1000 Index, NASDAQ-100 Index and the Russell 1000 Growth Stock Index. As of December 2021, Cisco had a market capitalization of around $267 billion.
By the time the company went public in 1990, Cisco had a market capitalization of $224 million by the end of the dot-com bubble in the year 2000, this had increased to $500 billion, surpassing Microsoft as the world's most valuable company. They pioneered the concept of a local area network (LAN) being used to connect distant computers over a multiprotocol router system. Ĭisco Systems was founded in December 1984 by Leonard Bosack and Sandy Lerner, two Stanford University computer scientists who had been instrumental in connecting computers at Stanford. Cisco is one of the largest technology companies in the world ranking 74 on the Fortune 100 with over $51 billion in revenue and nearly 80,000 employees. Cisco specializes in specific tech markets, such as the Internet of Things (IoT), domain security, videoconferencing, and energy management with leading products including Webex, OpenDNS, Jabber, Duo Security, and Jasper. Cisco develops, manufactures, and sells networking hardware, software, telecommunications equipment and other high-technology services and products. Ĭisco Systems, Inc., commonly known as Cisco, is an American-based multinational digital communications technology conglomerate corporation headquartered in San Jose, California.
