The smartphone market in the U.S. is officially blown up! - N.Y. Times
Nielsen’s third-quarter survey of mobile phone users found that 43 percent of them have upgraded to a smartphone. For mobile users below the age of 44, the smartphone is speeding toward mass adoption.
“This is a wake-up call for potential advertisers waiting for a tipping point for mobile media or for smartphones to reach the majority,” said Don Kellogg, director of telecom research and insights at Nielsen. “We’re already there with certain segments – 62 percent of those ages 25 to 34 already have smartphones. That’s critical mass.”
