Smartphone ownership has now reached the majority, albeit by a slim margin, says a Nielsen survey.

As of March, 50.4 percent of U.S. mobile subscribers owned a smartphone, up from 47.8 percent last December.

The smartphone is particularly attractive to adults age 25-34, with more than two out of three owning the mobile device, the survey finds.

Nielsen also says Apple was the top smartphone manufacturer, thanks to its popular iPhone, but Google's Android was the top smartphone operating system.

The survey found 48.5 percent of smartphone owners had a device running on Android, followed by 32 percent running iOS. Research in Motion's BlackBerry was a distant third with 11.6 percent.
