Apple and Samsung make up two-thirds of the U.S. smartphone market

Motorola, LG, and HTC are getting left in the dust, according to new data from research outfit NDP Group.

According to a study, Apple and Samsung account for a huge 68 percent of the smartphone market in the United States — and that’s a trend that’s only being magnified as time goes by.

As you can see above, wins for Apple and Samsung add up to losses for exactly everyone else.

iPhones alone captured 42 percent of the market, up from 35 percent in 2012. Samsung bumped up 4 percent year over year from 22 percent to 26 percent.

In terms of OS market share around the globe, however, Android is still the clear winner, capturing a whopping 81 percent.

HTC saw the biggest losses in terms of market share, and the all-time loser of 2013 was — drum roll — BlackBerry.

The report also shows a correlating spike in data usage from 5.5 GB to 6.6 GB per person a month between 2012 and 2013.

Also, more smartphones and more data usage mean one more big increase: streaming media. For streaming music alone, the percentage of people who stream media on their smartphones rose from 41 percent at the end of 2012 to 52 percent at the end of 2013.

“It’s not surprising that hardware manufacturers such as Beats are leveraging partnerships with carriers like AT&T to break into the streaming music market,” said John Buffone, an executive director, industry analyst, for connected intelligence, in a statement on the results.

“This allows AT&T to offer subscribers more of what they want in the way of innovative music apps and provides Beats a partner capable of driving trial in a market where consumers already have an affinity for the music services they use.”
