To the delight of advertisers everywhere, Mark Zuckerberg is growing increasingly obsessed with profits. That, as sources tell The Wall Street Journal, is what drove Facebook’s recent mobile innovations. “Mr. Zuckerberg has learned to embrace -- or at least accept -- the reality that he now is in charge of what might be bluntly described as the most visible advertising business in the world,” WSJ reports. “It is a big leap for the college dropout who wrote in a letter to potential investors just before the initial public offering: ‘Facebook was not originally created to be a company.’ ” 

Beginning 2014 with a bit of damage control, Snapchat is trying to reassure users that its recent data leak was a onetime glitch. “Changes will be made to both Snapchat’s apps and the service in order to prevent future leaks, including being able to opt out of the Find Friends feature that uses phone numbers,” TechCrunch reports, citing the company’s official statement. “Notably, Snapchat’s public response to this hacking does not include an apology of any sort.” 

Pointing toward an ever more fragmented world for media and marketers, wearable technology is expected to have a big year, in 2014. As yet, however, no single product has achieved mass-market success. “It’s an exploding product category in desperate need of a category-defining product,” as PCWorld puts it, before taking us through some potential candidates for consumers’ affections. 

Despite Google’s masterful marketing of Google Glass, Robert Scoble doesn’t think the wearable technology can success in 2014. Price is a big issue. “I'm hearing they won't be able to get under $500 in 2014, so that means it's doomed,” Scoble blogs. “In 2014,” he qualifies. “When they get under $300 and have another revision or two? That's when the market really will show up. 2016, I say.”
