Tech's Top 6 Celebrity CEOs

NEW YORK ( TheStreet) -- Silicon Valley is no stranger to larger-than-life personalities, with many of its high-flying CEOs making regular appearances in national headlines, celebrity gossip columns, blockbuster movies and in NBA floor-level seats.

Case in point was last week's double whammy of CEO reshuffling news, with the departure of Apple ( AAPL) CEO Steve Jobs on medical leave and Google's ( GOOG) new management regime making multiple headlines around the world.

Besides being worth millions -- if not billions -- of dollars, the guys that head Oracle ( ORCL), Cisco ( CSCO), Microsoft ( MSFT) and Dell ( DELL) share another trait: Fiery personalities and the willingness to fire shots at each others' products and company direction.

From Steve Ballmer's adrenalin-fueled stage-bounding to Larry Ellison's carefully calculated rival-baiting, there are plenty of tech executives vying for the national spotlight.

Read on for more on TheStreet's top tech celebrity CEOs.

John Chambers

Chambers became the face of the networking industry after assuming the Cisco CEO's role in 1995, growing the switch maker from $1.2 billion to its current run rate of $40 billion. Ubiquitous on the tech conference circuit, Chambers is one of the highest profile CEOs within the sector, and his keynotes and demos are a staple at events such as CES and Interop.

The voluble West Virginian, however, is not without his critics, and took plenty of flak after Cisco's less-than-stellar first-quarter results last year, which shook the tech sector. Cisco and Chambers, however, could be poised to rebound in 2011, boosted by cloud technology.

Chambers also remains popular within his own company, receiving an 85% approval rating from employees surveyed last year by career Web site

Outside of tech, Chambers has dabbled in the political arena, serving as co-chair of John McCain's presidential bid in 2008 and touted as a potential member of a McCain cabinet.

Eric Schmidt

The outgoing Google boss is a more understated presence, than say, Microsoft's Ballmer and Oracle's Ellison, but Eric Schmidt has enjoyed his own type of high profile.

Schmidt joined Google when it was still a startup in 2001, piloting its $1.67 billion IPO in 2004 and the company's subsequent growth into a $23.7 billion giant. In 2007, Schmidt oversaw the launch of the Android operating system, which has helped push the company's stock northward.

The Princeton grad has also been front and center in the net neutrality debate and was embroiled in a very public tussle over Internet censorship in China.

A frequent speaker on privacy issues, Schmidt is also a member of the President's Council of Advisors on Science and Technology. There was even post-election speculation that the Google CEO would be appointed as Obama's IT czar, although Schmidt publicly stated his desire to stay with the Internet giant.

The Google executive reshuffle came as a shock to industry observers. The less well-known Larry Page will replace Schmidt on April 4, and Schmidt will assume the role of executive chairman, serving as an advisor to Page and his fellow co-founder Sergey Brin.

Steve Ballmer

Ballmer took the Microsoft reins in 2000 from Bill Gates, and has since earned notoriety for his high-octane, sweat-drenched performances at the software giant's events.

One of America's richest people, with an estimated worth of $13.1 billion, Ballmer ranked 16th on the most recent version of the Forbes 400. Forbes also ranks Ballmer as 33rd on its list of the world's top billionaires.

Despite Ballmer's reputation for chest-beating, however, Microsoft shares have slipped more than 6% over the last 12 months as the company continues to play catch-up in the game of innovation and continues to try to make its mark in the mobile device market.

Ballmer has admitted that the software giant needs to get its act together in the mobile phone space, and has reshuffled the firm's consumer electronics and mobile businesses.

Michael Dell

One place ahead of Ballmer on the Forbes 400, Dell CEO Michael Dell has an estimated worth of $14 billion. Dell founded the eponymous PC maker with $1,000 in 1984, and in 1992 became the youngest CEO ever to earn a ranking on the Fortune 500.

As a company, however, Dell's fortunes have fluctuated over the years; its most recent results have been positive.

Michael Dell has also been grabbing the headlines thanks to his M&A strategy, spending almost $1 billion to acquire storage maker Compellent ( CML) after losing out to Hewlett-Packard ( HPQ) a high-profile battle for 3Par.

Another outspoken figure, Dell fired a now-famous jab at Apple in the nineties, when he said that the Mac maker's-then problems could be solved by closing the company and giving the money back to shareholders. Steve Jobs, however, had the last laugh in 2006 when Apple surpassed Dell's market cap.

Steve Jobs

Few CEOs personify their company as much as Steve Jobs, so last week's news that the iconic tech chief is taking another medical leave has raised big questions about Apple's future.

Famed for his black turtlenecks, jeans, and New Balance sneakers, Jobs is widely acclaimed as a technology visionary who helped save Apple when he returned to the Mac maker in the mid-nineties.

Adept at predicting shifts in popular culture, Jobs has used products such as the iPod, iPhone and iPad to reshape the consumer technology landscape

Even last year's Antennagate debacle and the lost iPhone prototype proved to be mere bumps in the road for the gadgetmaker, as Jobs quickly focused attention back onto the Apple corporate agenda.

"I think Steve Jobs is on the very short list of 20th and 21st-century CEOs whose hearts and souls seem indistinguishable from their company's products," Jay Newell, associate professor of advertising at Iowa State University, told TheStreet last year. "There are only a few executives in this mold, such as William Paley of CBS ( CBS) , Ted Turner of TBS, and Richard Branson of Virgin."

According to's recent research, Jobs is rated highly by Apple employees, receiving an approval rating of 97%.

The Apple boss, who also co-founded the animation studio Pixar, now part of Disney ( DIS), isn't afraid to opine against his rivals. Recent targets include rival tablet maker Research In Motion ( RIMM), Google and Adobe ( ADBE), which felt the force of Jobs' vitriol last year when he discredited their products.

Larry Ellison

One of tech's most combative figures, Ellison, like his close friend Jobs, is synonymous with the company he leads.

Ellison seems to love nothing more than talking trash about the competition. Last year the Oracle chief took a swing at HP's high-end server business and has even invited IBM ( IBM) to a Charles Bronson-style match-up, telling Big Blue to "make our day" in the battle for software supremacy.

With his penchant for yachts, planes and sports cars, Ellison is one of the most glamorous, albeit divisive, figures in Silicon Valley. "Ellison is a consummate competitor," Kaushik Roy, an analyst at Wedbush Morgan, told TheStreet last year. "Whether it's selling software or racing yachts, it seems he's always looking for a good fight."

Aside from the glitz and the glamour, though, the Oracle supremo has delivered results. The database maker's stock has climbed more than 159% in the last five years.
