SAN FRANCISCO—Google Inc.'s open-source Android is the most popular operating system among people in the U.S. who bought a smartphone in the past six months, according to data released Tuesday (Oct. 6) by the Nielsen Co.
Research in Motion Ltd.'s Blackberry operating system and Apple Inc.'s iOS were in a statistical dead heat among recent buyers, according to Nielsen, a media tracking company based in New York.
The Nielsen data covers a period that includes a full-month of iPhone 4 availability, the firm said. The iPhone 4 became available at the end of June.
Among all smartphone owners, Blackberry still holds the dominant share with 31 percent of the market, though its lead over Apple is declining, Nielsen said. Twenty-eight percent of smartphone owners have Apple iPhones, compared to 19 percent who have Android devices, according to Nielsen.
