The 15 most powerful tech companies in America

We recently released our list of the 50 most powerful companies in America.

Unsurprisingly, several tech companies topped the rankings. So we decided to sort them into a separate list to show which command the most power.

To determine each company’s level of power, we factored together fiscal 2014 revenue, number of employees, press mentions on Google News over the past year, and social media influence, as ranked on a scale of 1 to 100 by Klout, a site that analyses social-media influence of companies and individuals across all platforms. You can read the full methodology here.

E-commerce giant Amazon took the No. 1 spot on the list, followed by Microsoft at No. 2 and AT&T at No. 3. Interestingly, tech heavyweights Apple and Google missed the top three, but cinched the No. 4 and 6 spots, respectively.

2014 revenue: $US4.98 billion

Number of employees: 12,500

California-based Yahoo generated more than $US1 billion in new revenue in 2014 through its mobile, video, native, and social channels (aka Mavens). Yahoo now reaches 575 million mobile users, one of the largest mobile audiences globally.

Furthering its scope, Yahoo entered a partnership with Mozilla in late 2014 to use Yahoo.com as the default homepage for Firefox in the US. According to analytics site Alexa.com, Yahoo is the fifth most popular site in the world, and has a Klout score of 98 -- unsurprising for an internet giant.

11. Facebook

Facebook

2014 revenue: $US12.7 billion

Number of employees: 10,955

The pioneer of social media is now the
top social commerce platform, driving more than two-thirds of mobile e-commerce traffic. Thanks to ads on the site, revenue
was up 58% in 2014 for the Silicon Valley company.

This summer, Facebook's
market value topped $US250 billion, making it the fastest company to reach that high so quickly.

Ultimately, Facebook has incredible influence. In August, CEO Mark
Zuckerberg announced that 1 in 7 people on Earth used Facebook in a single day. Unsurprisingly, the social media giant has a high Klout score of 98.

9. Hewlett-Packard

Business Insider

2014 revenue: $US111.5 billion

Number of employees: 302,000

Hewlett-Packard isn't looking great after announcing that it will cut another 25,000 to 30,000 jobs, part of a huge multiyear layoff plan.

But being powerful isn't always about being well-liked, and the Palo Alto-based company remains a dominant corporation, especially considering that press mentions -- both positive and negative -- factored into our rankings. The company also rakes in a huge amount of revenue: over $US100 billion last year alone.

HP fares much better in terms of social media, however, with almost a million followers on Twitter and a Klout score of 92.

8. Intel

2014 revenue: $US55.25 billion

Number of employees: 106,700

Intel, headquartered in Santa Clara, California, is the world's leading semiconductor chipmaker with a market cap of $US140 billion. Apple has been using Intel chips for its computers since Steve Jobs announced the switch from IBM in 2005.

Last year, Intel lost billions of dollars going after its flailing mobile phone business, but now it's probable that Apple will replenish Intel's losses by allowing it to capture half of its modem business with this year's iPhone release.

Intel's undoubtedly doing well on social media, though, and commands a high Klout score of 96. It has 4.26 million Twitter followers and over 25 million fans on Facebook.

1. Amazon

2014 revenue: $US88.99 billion

Number of employees: 154,100

As the largest e-commerce site in the country, Amazon recently surpassed Walmart as the most valuable retailer in America in terms of market capitalisation.

The Seattle-based company currently owns over 40 subsidiaries, including Zappos, IMDb, and GoodReads, and refuses to be left behind in the consumer-electronics market.

Amazon debuted an e-reader and tablet to compete with Apple and launched Amazon Instant Video, which has produced an award-winning original television series. Amazon is tied with Microsoft for the highest Klout score on our list at 99 out of 100.
