> Year founded: 1979
EMC Corp. (NYSE: EMC) is known for its data storage systems. In the second quarter of 2013, EMC led the external disk storage systems market with a revenue share of 31.3%. EMC’s revenue totaled $5.6 billion, up only slightly from same time last year. Increases in the amount of data that consumers produce and companies record represent growing opportunities for the company. To address them, EMC recently divided its operations into three main businesses as part of a restructuring: information infrastructure business, VMware Virtual Infrastructure and EMC Pivotal. The creation of the new Pivotal division reflects the company’s efforts to remain competitive in the wake of rapid data developments in enterprise and consumer software, including cloud computing and big data.

> Year founded: 1939
Hewlett-Packard suffered a 9.4% year-over-year decline in shipments of large format printers between the second quarters of 2012 and 2013, according to IDC. Nevertheless, HP continues to be the undisputed leader in the market with a 39.4% market share, well above second place Canon. In the European PC market, the site of one of its core operations, HP is also the market leader. However, new expansions and products from companies like Lenovo will make the market more competitive. Bill Hewlett and Dave Packard founded HP in 1939. The one-car garage where the Stamford classmates founded the company in Palo Alto, Calif., is considered to be the birthplace of Silicon Valley.
> Lead industry: Semiconductors
> Market share: 16.4%
> Revenue last fiscal year: $53.3 billion
> Year founded: 1968
Founded in 1968 by two scientists, Robert Noyce and Gordon Moore, Intel produced the first microprocessor in 1971. Nearly 50 years later, Intel is the market leader in semiconductor sales, with a 16.4% share of the nearly $300 billion global market in 2012, according to Gartner. It was the 21st straight year that Intel was the industry’s worldwide market leader. In its most recent quarter, $8.1 billion of the company’s $12.8 billion in revenue came from its PC Client group, which produces chips for personal computers. The unit’s sales declined 5% from the previous year, likely due in part to the growing use of tablets and smartphones.
> Lead industry: Ethernet switches
> Market share: 62.2%
> Revenue last fiscal year: $46.1 billion
> Year founded: 1984
Cisco Systems Inc. (NASDAQ: CSCO) provides a variety of products and services, but it is the market leader for Ethernet switches, devices that facilitate the transfer of data between computer networks. The company, founded by two Stanford computer scientists in 1984 and named after San Francisco, was the originator of the multi-protocol router, which allowed local connected networks, like an office network, to connect to disparate networks, such as networks in other buildings across the street or the country. Cisco’s market share was 62.2% in the second quarter of 2013, the same as the preceding quarter. According to IDC, Cisco’s market share in the fast growing 10 gigabit Ethernet market segment was 67% in the second quarter of 2013. The new 10GbE switch, which offers about 10 times the bandwidth of the 1GbE, has fallen in cost recently, causing record growth rates in this market.

> Year founded: 1975
Microsoft holds a dominant market share for PC operating systems. Between its Windows XP, Windows Vista, Windows 7 and Windows 8 systems, the company had more than a 91% market share as of August, according to Net Market Share. The company first released a Windows-branded operating system in 1985. While it effectively controls operating systems for the PC market, it still faces an uphill battle to find similar success in the smartphone market. As of the second quarter of 2013, less than 4% of smartphone shipments used the Windows Phone operating system, while nearly 80% used Google Inc.’s (NASDAQ: GOOG) Android. In order to push further into the smartphone market, Microsoft recently purchased Finnish giant Nokia Corp.’s (NYSE: NOK) phone business.
> Lead industry: Servers
> Market share: 25.6%
> Revenue last fiscal year: $104.5 billion
> Year founded: 1911
As of 2012, IBM was the dominant producer of mainframes, such as the System z, which are powerful servers that often start at more than $1 million. But in the overall server market, where IBM still holds a narrow lead over HP, its share of the market is waning. IBM barely beat out HP for server sales, with 25.6% of the market by revenue, in the second quarter of 2013, versus HP’s 25.0%. The majority of the company’s systems and technology offerings, which include servers, had declining revenue in the last quarter versus the year before. IBM is hardly the only company experiencing such a slowdown — worldwide server revenue declined nearly 4% year-over-year in the third quarter of 2013. But servers are hardly IBM’s only business, accounting for just $3.8 billion of the company’s $24.9 billion in revenue last quarter.
