Overtook BlackBerry in the last six months.
The Nielsen Company has published research claiming that Android accounted for 32% of new smartphones bought in the US between January and August this year.
That means Google's OS has overtaken BlackBerry, which joins iPhone in a "statistical dead heat" for second place among those recent acquirers.
Nielsen points out that the data includes a full month of iPhone 4 availability.
However, when it comes to all smartphone owners, BlackBerry is still top dog in the US with a 31% market share, although Apple is up to 28%, and Android climbing fast with 19%.
The data is not the first to suggest that Android has overtaken BlackBerry for new smartphone sales in the US.
However, rather than jump in with 'Android killing RIM or Apple' stories, we'd suggest that the data shows all three operating systems continue to have significant shares of new US buyers.
It remains a three-horse race, and that's before the launch of Microsoft's Windows Phone 7, which is due later this month.
