Most of the top brass at the nation's largest technology-focusedcompanies are nowhere to be found on social media, at least in anofficial capacity.

That's the finding released this week by Augure, a provider ofinfluence marketing software founded in Paris in 2002 and nowclaiming a client list of more than 1,500 companies andagencies.

The company said its research found that only 30% of theexecutive directors at NASDAQ 100 companies, including CEOs, areactive on social media, and that Apple, for instance, has noofficial social network presence at all, although its CEO Tim Cookdoes have a Twitter account and, with 248,000 online media hits inthe past year, he is the most influential leader across social andonline media.

Among company directors, 23% use LinkedIn, Agure said itsresearch found, making it the most widely used social network.

In second place is Twitter, with 11%, followed by Google+ andFacebook, with 8% and 5%, respectively.

“Only (Yahoo's) Marissa Mayer and (Tesla's) Elon Musk have anofficial Facebook page while Philippe Dauman of Viacom and ShantanuNarayen of Adobe have personal profiles on the platform,” Auguresaid in a news release this week.

“It is surprising to find just a 30% of the CEOs of NASDAQinvolved in social media, making use of the new technology andworking on its influence as leaders of these powerful andtechnological companies,” said Augure CEO Michael Jais.
