This year’s Super Bowl will likely attract the largest audience and the most ad revenue in NFL history. NBC sold out all of its Super Bowl ad slots, which cost $4.5 million for 30 seconds of airtime (a record). And online gambling website Vegas Insider placed the over-under on the number of Super Bowl viewers at 113 million, which would be the largest audience in the history of U.S. television.

Vine is today introducing a new layer of the service called Vine Kids. It’s meant to be a safe, kid-friendly space for a younger audience to play around with the app and watch vines.

The app pulls from the millions of Vines being created on the platform and chooses ones that are appropriate for children. The interface of the Kids section of the app has also been tailored to be more fun for children, showing a new Vine each time the user swipes left or right and playing “quirky” sounds each time the user taps the screen.

Despite a user base of nearly 300 million, Twitter recently announced plans to ramp up new account signups, along with a host of other offerings aimed at both individual and business customers. Reporting from Twitter’s first Analyst Day event in November, 2014, Mashable’s Seth Fiegerman said the company “plans to speed up its product development process to ease the onboarding process, broaden content syndication efforts, expand the overall app ecosystem and continue building up ad products.”

If you’re useless at writing computer code, does the tech sector still want to hire you? Yes — big-time — says LinkedIn analytics manager Andrew Kritzer, who has just completed a comprehensive analysis of job-hoppers’ moves in 2014.

In a blog post, Kritzer singles out a wide-range of non-technical skills that suddenly have allure for fast-growing digital businesses. For example, he says, Internet companies are snapping up brand-management experts who earned their chops by working in retailing. E-learning companies are hiring people who used to be principals, teachers or school superintendents.

A recent flurry of mobile-related changes in the social media industry means we're about to witness yet another transformation. Are you up to speed?

If content creation is a digital marketing trend for 2015, then Tumblr is ahead of the game. Last week the blogging platform announced that it will launch an ad network called the Creatrs Network. Through partnerships with Tumblr-based social influencers, brands will be able to gain access to curated and original content for use in their Tumblr campaigns. If they so choose, they'll also have the ability to distribute the content in ad-form to audiences on Yahoo, Facebook, and Instagram.
