The State of Mobile in the U.S. (Infographic)

As the smartphone market expands, it creates opportunities for other industries, particularly in the e-commerce and application spaces. Indeed, these two sectors have grown with smartphone penetration. An infographic from mobile programmatic display advertising firm Sociomantic Labs provides insight into this growth.

Smartphone penetration in the U.S. has grown from just under 70 percent in 2014 to an estimated almost 80 percent this year. Android still seems to be in the lead when it comes to operating systems, capturing more than one-half of the market, compared with 43 percent for iOS. Mobile devices also now account for more than 54 percent of all web traffic.

Mobile commerce may also be on an even steeper trajectory than smartphone adoption, with an estimated $123 billion in sales this year, more than double the 2014 total. What's more, an estimated 32 percent of all e-commerce retail sales will come from mobile devices in 2016, further cementing the relationship between device and user behavior.

While smartphone shoppers use apps regularly, the uninstall problems persist. 45 percent of consumers have made a purchase through an app, and 43 percent of smartphone shoppers use their apps on a weekly basis. However, 25 percent of apps installed are never used, and another 25 percent are used only once. App stickiness is higher these days, but it's clear that if an app doesn't engage users immediately, it will likely be discarded.

Apps are also a key touchpoint on the path to purchase. 50 percent of users look to apps during their path, with 45 percent of these users searching for product information, and 29 percent of them using apps to make their purchase.
