Cisco Systems was founded in December 1984 byLeonard Bosack andSandy Lerner, twoStanford University computer scientists who had been instrumental in connecting computers at Stanford. They pioneered the concept of alocal area network (LAN) being used to connect distant computers over a multiprotocolrouter system. The company went public in 1990 and, by the end of thedot-com bubble in 2000, had a market capitalization of $500 billion, surpassingMicrosoft as the world's most valuable company.[5][6]
Cisco's initial product has roots in Stanford University's campus technology. 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".[10] The Blue Box used circuitry made byAndy Bechtolsheim, and software that was originally written at Stanford by research engineerWilliam Yeager.[10] Due to the underlying architecture, and its ability to scale well, Yeager's well-designed invention became a key to Cisco's early success.[11]
In 1985, Bosack and Stanford employee Kirk Lougheed began a project to formally network Stanford's campus.[10] They adapted Yeager's software into what became the foundation forCisco IOS, despite Yeager's claims that he had been denied permission to sell the Blue Box commercially. 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.[10] In 1987, Stanford licensed the router software and two computer boards to Cisco.[10] In addition to Bosack, Lerner, Lougheed, Greg Satz (a programmer), and Richard Troiano (who handled sales), completed the early Cisco team.[10] The company's first CEO was Bill Graves, who held the position from 1987 to 1988.[12] In 1988,John Morgridge was appointed CEO.[13]
The name "Cisco" was derived from the city nameSan Francisco, which is why the company's engineers insisted on using the lower case "cisco" in its early years.[14] The logo is a stylized depiction of the two towers of theGolden Gate Bridge.[1]
On February 16, 1990, Cisco Systems went public with a market capitalization of $224 million, and was listed on theNASDAQ stock exchange. On August 28, 1990, Lerner was fired. Upon hearing the news, her husband Bosack resigned in protest.[15]
Although Cisco was not the first company to develop and sell dedicated network nodes,[16] it was one of the first to sell commercially successful routers supporting multiple network protocols.[17] Classical, CPU-based architecture of early Cisco devices coupled with flexibility of operating systemIOS allowed for keeping up with evolving technology needs by means of frequent software upgrades. Some popular models of that time (such asCisco 2500) managed to stay in production for almost a decade virtually unchanged. The company was quick to capture the emerging service provider environment, entering the SP market with product lines such as Cisco 7000 and Cisco 8500.[18]
Between 1992 and 1994, Cisco acquired several companies inEthernet switching, such asKalpana,[19] Grand Junction[20] and most notably,Mario Mazzola's Crescendo Communications,[21] which together formed theCatalyst business unit. At the time, the company envisionedlayer 3 routing andlayer 2 (Ethernet,Token Ring) switching as complementary functions of different intelligence and architecture—the former was slow and complex, the latter was fast but simple. This philosophy dominated the company's product lines throughout the 1990s.[18]
TheInternet Protocol (IP) became widely adopted in the mid-to-late 1990s.[23] Cisco introduced products ranging from modem access shelves (AS5200) to coreGSR routers, making them a major player in the market.[23] In late March 2000, at the height of thedot-com bubble, Cisco became the most valuable company in the world, with amarket capitalization of more than $500 billion.[5][24] As of July 2014, with a market cap of about US$129 billion,[25] it was still one of the most valuable companies.[26]
The perceived complexity of programming routing functions in silicon led to the formation of several startups determined to find new ways to process IP andMPLS packets entirely in hardware and blur boundaries between routing and switching. One of them,Juniper Networks, shipped their first product in 1999 and by 2000 chipped away about 30% from Cisco SP Market share. In response, Cisco later developed homegrownASICs and fast processing cards for GSR routers andCatalyst 6500 switches. In 2004, Cisco also started the migration to new high-end hardwareCRS-1 and software architectureIOS XR.[27]
As part of a rebranding campaign in 2006, Cisco Systems adopted the shortened name "Cisco" and created "The Human Network" advertising campaign.[29] These efforts were meant to make Cisco a "household" brand—a strategy designed to support the low-end Linksys products and future consumer products.[18]
On the more traditional business side, Cisco continued to develop its routing, switching and security portfolio. The quickly growing importance ofEthernet also influenced the company's product lines. Limits ofIOS and aging Crescendo architecture also forced Cisco to look at merchant silicon in the carrier Ethernet segment. This resulted in a newASR 9000 product family intended to consolidate the company's carrier Ethernet and subscriber management business aroundEZChip-based hardware andIOS-XR.[18]
In March 2007, Cisco acquired Reactivity Inc, a privately held XML gateway provider based inRedwood City, California. Cisco placed the Reactivity team and product portfolio under its Datacenter Switching and Security Technology Group, which reported to the company's then senior vice presidentJayshree Ullal.[30]
Throughout the mid-2000s, Cisco also built a significant presence in India, establishing its Globalization Centre East inBangalore for $1 billion.[31] Cisco also expanded into new markets by acquisition—one example being a 2009 purchase of mobile specialistStarent Networks.[32]
Cisco continued to be challenged by both domestic competitorsAlcatel-Lucent,Juniper Networks, and an overseas competitorHuawei. Due to lower-than-expected profit in 2011, Cisco reduced annual expenses by $1 billion. The company cut around 3,000 employees with an early-retirement program who accepted a buyout and planned to eliminate as many as 10,000 jobs (around 14 percent of the 73,400 total employees before curtailment).[33][34] During the 2011 analyst call, Cisco's CEO John Chambers called out several competitors by name,[35] including Juniper and HP.
On July 24, 2012, Cisco received approval from theEU to acquire NDS (a TV software developer) for US$5 billion.[36] In 2013, Cisco sold its Linksys home-router unit to Belkin International Inc., signaling a shift to sales to businesses rather than consumers.[37]

On July 23, 2013, Cisco Systems announced a definitive agreement to acquireSourcefire for $2.7 billion.[38] On August 14, 2013, Cisco Systems announced it would cut 4,000 jobs from its workforce, which was roughly 6%, starting in 2014.[39] At the end of 2013, Cisco announced poor revenue due to depressed sales in emerging markets, caused by economic uncertainty and by fears of theNational Security Agency planting backdoors in its products.[40]
In April 2014, Cisco announced funding for early-stage firms to focus on the Internet of Things. The investment fund was allocated to investments in IoT accelerators and startups such as The Alchemist Accelerator, Ayla Networks andEVRYTHNG.[41] Later that year, the company announced it was laying off another 6,000 workers or 8% of its global workforce, as part of a second restructuring.[42] On November 4, 2014, Cisco announced an investment inStratoscale.[43]
On May 4, 2015, Cisco announcedCEO and ChairmanJohn Chambers would step down as CEO on July 26, 2015, but remain chairman.Chuck Robbins, senior vice president of worldwide sales & operations and 17-year Cisco veteran, was announced as the next CEO.[44] On July 23, 2015, Cisco announced the divestiture of its television set-top-box andcable modem business toTechnicolor SA for $600 million,[45] a division originally formed by Cisco's $6.9 billion purchase ofScientific Atlanta. The deal came as part of Cisco's gradual exit from the consumer market, and as part of an effort by Cisco's new leadership to focus on cloud-based products in enterprise segments. Cisco indicated that it would still collaborate with Technicolor on video products.[46] On November 19, 2015, Cisco, alongsideARM Holdings,Dell,Intel,Microsoft andPrinceton University, founded theOpenFog Consortium, to promote interests and development infog computing.[47]

Cisco acquired a variety of companies to spin products and talent into the company. In 1995–1996 the company completed 11 acquisitions.[93] Several acquisitions, such asStratacom,[94] were one of the biggest deals in the industry when they occurred.[95] During the Internet boom in 1999, the company acquiredCerent Corporation, a start-up company located inPetaluma, California, for about US$7 billion.[96] It was the most expensive acquisition made by Cisco to that date, and only the acquisition ofScientific Atlanta has been larger.[97] In 1999, Cisco also acquired a stake for $1 billion in KPMG Consulting to enable establishing Internet firm Metrius founded by Keyur Patel of Fuse.[98] Several acquired companies have grown into $1Bn+ business units for Cisco, including LAN switching, EnterpriseVoice over Internet Protocol (VOIP) platformWebex andhome networking. The latter came as result of Cisco acquiringLinksys in 2003 and in 2010 was supplemented with new product line dubbedCisco Valet.

Accordingly,IronPort was integrated into the Cisco Security business unit.[103] Ironport's Senderbase was renamed as Sensorbase to take account of the input into this database that other Cisco devices provide.[104] SensorBase allows these devices to build a risk profile on IP addresses, therefore allowing risk profiles to be dynamically created on http sites and SMTP email sources.[105]
In 2010, Cisco boughtStarent Networks (a mobile packet core company) for $2.9 billion[106][107] and Moto Development Group, a product design consulting firm that helped develop Cisco's Flip video camera.[108][109] Also in 2010, Cisco became a key stakeholder ine-Skills Week. In March 2011, Cisco completed the acquisition of privately held network configuration and change management software company Pari Networks.[110]
Although many buy-ins (such as Crescendo Networks in 1993,Tandberg in 2010) resulted in acquisition of flagship technology to Cisco, many others have failed—partially or completely.[111] For instance, in 2010 Cisco occupied a meaningful share of the packet-optical market,[112] revenues were still not on par with US$7 billion price tag paid in 1999 forCerent. Some of acquired technologies (such as Flip from Pure Digital) saw their product lines terminated.[113][114]
