Google’s Android controlled nearly two-thirds of the United States smartphone market in the year’s first quarter.

According to CNET, market research firm NPD Group placed Android’s U.S. market share at 61 percent, which is a dramatic gain from the holiday quarter’s 49 percent.

Meanwhile, Apple’s iOS slid from 41 percent in Q4 2011 to 29 percent in Q1 2012. It is assumed Apple’s October iPhone 4S launch boosted the holiday sales, but Android eventually reclaimed its Q3 2011 crown once the new year settled.

It is worth mentioning that advertising research company Neilsen measured the two smartphone OS manufacturers in March and placed Android at 49.5-percent and iOS at 32 percent for Q1 2012.
