Since Apple launched the iPhone in 2007, smartphones have really taken off , and more than 1 billion people worldwide now own one. Last year alone, smartphones generated $293.9 billion in sales, but the cost of the average smartphone has begun falling.
More than half of cellphone owners in the U.S. and other developed markets already own a smartphone, and those in emerging markets such as China and India aren’t able to pay for high-end devices like the iPhone. As a result, cheaper options are becoming increasingly popular.
