Two years ago I wrote an iHealthBeat Perspective, titled, "Social Media in Health Care: Barriers and Future Trends." Let's take a look at how far we have come and whether my predictions are on target.

The share of Web site traffic on tablets grew more than 300% in the past year, according to research released Tuesday. Tablets' share of Web site traffic will exceed smartphone traffic by early 2013, reaching 10% of total Web site traffic in 2014.

Mobile devices are increasingly used as a mother’s helper when her kids are bored. Research shows that moms, anxious to keep their offspring quiet and occupied, share their smartphones with children as young as age 1.

The key change, one that marketers often overlook, is that Millennials just aren’t kids anymore. In fact, according to our Millennial Life Stage Segmentation, only one in ten Millennials (11% of Millennials or approximately 10 million) isn’t an official adult (i.e., is under the age of 18). Approximately 13 million, or 15%, are college students and about 12 million, or 14%, are in flux – not working or married, but don’t have kids. The majority of Millennials are “grown-ups” in the way society tends to define them—they are working (36% or 31 million) or parents (24% or 21 million).

The implications for healthcare? Both the power of mobile and the power of Big Data could not be achieved without the added innovation of cloud computing. Storage of information in the cloud and access on mobile devices allows for those devices to truly be windows into the world of information (ever notice how ‘dumb’ your iPad seems when it’s not connected to the Internet?). All of that Big Data is stored in the Cloud. These three innovations rely on one another for success.
