Last year, 2011, was a big one for mobile health. MobiHealthNews tracked more than 100 deals and partnerships throughout the year and about 60 venture capital investments. We tracked more than half a billion dollars in investments into mobile health companies during the past year. While there were a handful of massive deals, including the $75 million ZocDoc raised over the course of 2011, most of the investment deals were for a couple million each.

The total investment in mobile health-related companies in 2011 was more than twice as much as total investment in 2010. As MobiHealthNews reported about a year ago, the total investment in mHealth companies in 2010 was $233 million. There were also only a little more than a dozen announced investment rounds in 2010. In 2011 there were about four times that many. It also brought in dozens of new investment firms.
